There is a colony of 8 cells arranged in a straight line where each day every cell competes with its adjacent cells(neighbour). Each day, for each cell, if its neighbours are both active or both inactive, the cell becomes inactive the next day,. otherwise itbecomes active the next day.
Assumptions: The two cells on the ends have single adjacent cell, so the other adjacent cell can be assumsed to be always inactive. Even after updating the cell state. consider its pervious state for updating the state of other cells. Update the cell informationof allcells simultaneously.
Write a fuction cellCompete which takes takes one 8 element array of integers cells representing the current state of 8 cells and one integer days representing te number of days to simulate. An integer value of 1 represents an active cell and value of 0 represents an inactive cell.
Program:
int* cellCompete(int* cells,int days)
{
//write your code here
}
//function signature ends
Test Case 1:
INPUT:
[1,0,0,0,0,1,0,0],1
EXPECTED RETURN VALUE:
[0,1,0,0,1,0,1,0]
Test Case 2:
INPUT:
[1,1,1,0,1,1,1,1,],2
EXPECTED RETURN VALUE:
[0,0,0,0,0,1,1,0]
This is the problem statement given above for the problem. The code which I have written for this problem is given below. But the output is coming same as the input.
#include
using namespace std;

I am not able to get the error and I think my logic is wrong. Can we apply dynamic programming here If we can then how?
Answers
Answer:
I am writing a C++ program using loops instead of nested if statements.
#include <iostream> // to use input output functions
using namespace std; // to identify objects like cin cout
void cells(int cells[],int days){ /* function that takes takes one array of integers cells, one integer days representing the number of days to simulate. */
int pos ,num=0; //declares variables pos for position of two adjacent cells and num to iterate for each day
int result[9]; //the updated output array
while (num< days) { //this loop keeps executing till the value of num is less than the value of number of days
num++;
for(pos=1;pos<9;pos++) //this loop has a pos variable that works like an index and moves through the cell array
result[pos]=(cells[pos-1])^ (cells[pos+1]); //updated cell state determined by the previous and next cells (adjacent cells) by bitwise XOR operations
for(pos=1;pos<9;pos++) //iterates through the array
cells[pos]=result[pos]; } //the updated cells state is assigned to the cell array simultaneously
for(pos=1;pos<9;pos++) //iterates through the array and prints the resultant array that contains the updated active and inactive cells values
cout << result[pos]; }
int main() { //start of the main function body
int j,day;
int output[9];
*/the two cells on the ends (first and last positions of array) have single adjacent cell, so the other adjacent cell can be assumed to be always inactive i.e. 0 */
output[0]=output[9]=0;
for(j=1;j<9;j++) //takes the input array from user
cin >> output[j];
cin >> day;
cells(output,day); } //calls the function cells to print the array with active and inactive cells states.
Explanation:
The program is well explained in the comments mentioned with every statement of the program. I will explain with the help of example:
Suppose the user enters the array = [1,0,0,0,0,1,0,0] and days=1
The while loop checks if the value of num is less than that of days. Here num is 0 and days is 1 So this means that the body of while loop will execute.
In the body of while loop the value of num is incremented by 1. The first loop initializes a variable pos for position of adjacent cells. The statement is a recursive statement result[pos]=(cells[pos-1])^ (cells[pos+1]) that uses previous state for updating the state of other cells. The “^” is the symbol used for bitwise exclusive operator. In bitwise XOR operations the two numbers are taken as operands and XOR is performed on every bit of two numbers. The result of XOR is 1 if the two bits are not same otherwise 0. For example XOR of 1^0 and 0^1 is 1 and the XOR of 0^0 and 1^1 is 0. The second for loop update the cell information of all cells simultaneously. The last loop prints the updated cells states.
The main function takes the input array element from user and the value for the days and calls the cells function to compute the print the active and inactive cells state information.
The screenshot of the program along with its output are attached.

Suppose that an engineer excitedly runs up to you and claims that they've implemented an algorithm that can sort n elements (e.g., numbers) in fewer than n steps. Give some thought as to why that's simply not possible and politely explain
Answers
Answer:
The summary including its given problem is outlined in the following section on the interpretation.
Explanation:
That's not entirely feasible, since at least n similarities have to be made to order n quantities. Find the finest representation where the numbers of 1 to 10 have already been arranged.
⇒ 1 2 3 4 5 6 7 8 9 10
Let's say that we identify one figure as the key then compared it towards the numbers across the left. Whether the correct number is greater, therefore, left number, are doing nothing to switch the location elsewhere.
Because although the numbers have already been categorized 2 has always been compared to 1 which would be perfect, 3 becomes especially in comparison to 2 and so much more. This should essentially take 9 moves, or nearly O(n) moves.
If we switch that little bit already
⇒ 1 3 2 4 5 6 7 8 9 10
3 Is contrasted with 1. 2 will indeed be matched against 3 as well as 2. Since 2 has indeed been exchanged, it must, therefore, be matched with 1 as there might be a case whereby each number z exchanged is greater than the number Y as well as the quantity X < Y.
X = 1, Y = 3, and Z = 2.Only one adjustment expanded the steps which culminated in n+1.
It should be noted that it won't be possible because at least n similarities have to be made to order n quantities.
From the information given, it should be noted that it's not possible for the engineer to implement an algorithm that can sort n elements (e.g., numbers) in fewer than n steps.
This is because there are at least n similarities have to be made to order n quantities. In this case, the numbers of 1 to 10 have already been arranged. When a number is greater, it should be noted that the left number will do nothing to switch the location elsewhere.
Therefore, the information given by the engineer isn't feasible.

Explanation:
A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right.
For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation.
Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input.
The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position.
The script shiftRight performs the inverse operation.
Each script prints the resulting string.
An example of shiftLeft.py input and output is shown below:
Enter a string of bits: Hello world!

3.16 (Gas Mileage) Drivers are concerned with the mileage obtained by their automobiles. One driver has kept track of several tankfuls of gasoline by recording miles driven and gallons used for each tankful. Develop a program that will input the miles driven and gallons used for each tankful. The program should calculate and display the miles per gallon obtained for each tankful. After processing all input information, the program should calculate and print the combined miles per gallon obtained for all tankfuls. Here is a sample input/output dialog:
Answers
Answer:
I am writing a C program.
#include <stdio.h> // for using input output functions
#include <stdbool.h> // for using a bool value as data type
int main() { // start of the main() function body
int count=0; //count the number of entries
double gallons, miles, MilesperGallon, combined_avg, sum; //declare variables
while(true) {// takes input gallons and miles value from user and computes avg miles per gallon
printf( "Enter the gallons used (-1 to stop): \n" ); //prompts user to enter value of gallons or enter -1 to stop
scanf( "%lf", &gallons );//reads the value of gallons from user
if ( gallons == -1 ) {// if user enters -1
combined_avg = sum / count; //displays the combined average by dividing total of miles per drives to no of entries
printf( "Combined miles per gallon for all tankfuls: %lf\n", combined_avg ); //displays overall average value
break;} //ends the loop
printf( "Enter the miles driven: \n" ); //if user does not enter -1 then prompts the user to enter value of miles
scanf( "%lf", &miles ); //read the value of miles from user
MilesperGallon = miles / gallons; //compute the miles per gallon
printf( "The miles per gallon for tankful: %lf\n", MilesperGallon ); //display the computed value of miles per gallon
sum += MilesperGallon; //adds all the computed miles per gallons values
count += 1; } } //counts number of tankfuls (input entries)
Explanation:
The program takes as input the miles driven and gallons used for each tankful. These values are stored in miles and gallons variables. The program calculates and displays the miles per gallon MilesperGallon obtained for each tankful by dividing the miles driven with the gallons used. The while loop continues to execute until the user enters -1. After user enters -1, the program calculates and prints the combined miles per gallon obtained for all tankful. At the computation of MilesperGallon for each tankful, the value of MilesperGallon are added and stored in sum variable. The count variable works as a counter which is incremented to 1 after each entry. For example if user enters values for miles and gallons and the program displays MilesperGallon then at the end of this iteration the value of count is incremented to 1. This value of incremented for each tankful and then these values are added. The program's output is attached.

Explanation:
The program is elaborated in the comments with each statement of the above code. The program has a class Plane that has a method CheckIn to handle the check in process. The user is prompted to enter a choice i.e. enter 1 to select First Class Seat and enter 2 to select Economy Seat. A switch statement is used to handle this process. If user enters 1 then the case 1 of switch statement executes which reserves a seat for the user in first class. If user enters 2 then the case 2 of switch statement executes which reserves a seat for the user in economy class.There are only 5 seats for each First Class and Economy. So when the limit of the seats reservation exceeds 5 then the no more seats available for you selection is displayed. If all the seats are taken in both the first and economy class then it displays the message All seats are reserved. If the user enters anything other than 1 or 2 then display the message Enter a valid choice. Whenever the user reserves one of first or economy class seats the relevant seat is incremented to 1 in order to count the number of seats being reserved. The program and its output are attached.

Editing the subject line is very important so as to enable the recipient know the source of received the message (document).
For example, if a remote team working on a project called Project X receives a shared document by one member of team, we would expect the subject line of the email to be– Project X document. By so doing the legitimacy of the email is easily verified.

Answers
Answer:
Here is the function PrintSongsShorterThan() which prints all the songs from the album shorter than the value of the parameter songDuration.
void Album::PrintSongsShorterThan(int songDuration) const {
unsigned int i;
Song currSong;
cout << "Songs shorter than " << songDuration << " seconds:" << endl;
for(int i=0; i<albumSongs.size(); i++){
currSong = albumSongs.at(i);
if(currSong.GetDuration()<songDuration){
currSong.PrintSong(); } } }
Explanation:
I will explain the working of the for loop in the above function.
The loop has a variable i that is initialized to 0. The loop continues to execute until the value of i exceeds the albumSongs vector size. The albumSongs is a Song type vector and vector works just like a dynamic array to store sequences.
At each iteration the for loop checks if the value of i is less than the size of albumSongs. If it is true then the statement inside the loop body execute. The at() is a vector function that is used to return a reference to the element at i-th position in the albumSongs. So the album song at the i-th index of albumSongs is assigned to the currSong. This currSong works as an instance. Next the if condition checks if that album song's duration is less than the specified value of songDuration. Here the method GetDuration() is used to return the value of duration of the song. If this condition evaluates to true then the printSong method is called using currSong object. The printSong() method has a statement cout << name << " - " << duration << endl; which prints/displays the name of the song with its duration.
If you see the main() function statement: musicAlbum.PrintSongsShorterThan(210);
The musicAlbum is the Album object to access the PrintSongsShorterThan(210) The value passed to this method is 210 which means this is the value of the songDuration.
As we know that the parameter of PrintSongsShorterThan method is songDuration. So the duration of each song in albumSongs vector is checked by this function and if the song duration is less than 210 then the name of the song along with its duration is displayed on the output screen.
For example if the album name is Anonymous and the songs name along with their duration are:
ABC 400
XYZ 123
CDE 300
GHI 200
KLM 100
Then the above program displays the following output when the user types "quit" after entering the above information.
Anonymous
Songs shorter than 210 seconds:
XYZ - 123
GHI - 200
KLM - 100
Notice that the song name ABC and CDE are not displayed because they exceed the songDuration i.e. 210.
The output is attached.

1| def saveUserProfile(firstName, lastName, age, height, country):
2| filename = lastName + firstName + ".txt"
3| outputFile = open(filename, "w")
4| print(lastName, file = outputFile)
5| print(firstName, file = outputFile)
6| print(country, file = outputFile)
7| print(height, file = outputFile)
8| print(age, file = outputFile)
9| outputFile.close()
Above is a function that takes five pieces of information about a user and saves that data to a file. We'll assume firstName, lastName, and country are strings, age is an integer, and height (expressed in meters) is a float.
Assume we call the function above with this line of code:
saveUserProfile("David", "Joyner", 30, 1.8, "USA")
After the function runs, what is name of the file that is created?
a. What is written on line 1 of that file? If there is no line 1 or if line 1 is blank, enter Nothing.
b. What is written on line 2 of that file? If there is no line 2 or if line 2 is blank, enter Nothing.
c. What is written on line 3 of that file? If there is no line 3 or if line 3 is blank, enter Nothing.
d. What is written on line 4 of that file? If there is no line 4 or if line 4 is blank, enter Nothing.
e. What is written on line 5 of that file? If there is no line 5 or if line 5 is blank, enter Nothing.
Answers
Answer:
Joyner
David
USA
1.8
30
Explanation:
def saveUserProfile(firstName, lastName, age, height, country):
This is the definition of function named saveUserProfile which accepts the following parameters:
firstNamelastNameageheightcountryfilename = lastName + firstName + ".txt"
When the file is created it will be named as the lastName and firstName string combined with .txt as extension. For example if the lastName contains the name string Joyner and firstName contains the name David then the file created to be written is named as JoynerDavid.txt
outputFile = open(filename, "w")
This statement uses open() method in write mode and uses outputFile object to access the file. "w" represents write mode i.e. file is opened in write mode to write on it.
a) Joyner is written on line 1 of that file because of the following statement of above function:
print(lastName, file = outputFile)
This statement prints the string stored in lastName i.e. Joyner. Here outputFile opens the file in "w" write mode and writes the last name to the first line of the file.
b) David is written on line 2 of that file because of the following statement of above function:
print(firstName, file = outputFile)
This statement prints the string stored in firstName i.e. David. Here outputFile opens the file in "w" write mode and writes the first name to the second line of the file.
c) USA is written on line 3 of that file because of the following statement of above function:
print(country, file = outputFile)
This statement prints the data stored in country i.e. USA. Here outputFile opens the file in "w" write mode and writes the country name to the third line of the file.
d) 1.8 is written on line 4 of that file because of the following statement of above function:
print(height, file = outputFile)
This statement prints the value stored in height i.e. 1.8. Here outputFile opens the file in "w" write mode and writes the height value to the fourth line of the file.
e) 30 is written on line 5 of that file because of the following statement of above function:
print(age, file = outputFile)
This statement prints the value stored in age parameter of function saveUserProfile i.e. 30. Here outputFile opens the file in "w" write mode and writes the age value to the fifth line of the file.
An organization is struggling to differentiate threats from normal traffic and access to systems. A security engineer has been asked to recommend a system that will aggregate data and provide metrics that will assist in identifying malicious actors or other anomalous activity throughout the environment. Which of the following solutions should the engineer recommend?a. Web application firewall b. SIEM c. IPS d. UTM e. File integrity monitor
Answers
Answer:
b. SIEM.
Explanation:
In this scenario, an organization is struggling to differentiate threats from normal traffic and access to systems. A security engineer has been asked to recommend a system that will aggregate data and provide metrics that will assist in identifying malicious actors or other anomalous activity throughout the environment. The solution the engineer should recommend is the Security information and event management (SIEM).
Security information and event management is an enterprise software that provides a holistic view and analyzes activity from various resources across an entire information technology (IT) infrastructure.
The SIEM is used to aggregate important data from multiple source such as servers, routers, firewall, switches, domain controllers, antivirus software and analyzes the data to detect any threat, deviation from the norm, as well as investigate in order to take appropriate actions. Some examples of the SIEM system are IBM QRadar, Splunk, LogRhythm etc.
