Defining a Figure of Merit
Consider a string-matching figure of merit. That is, it tells you how close to a given string another string is. Each matching letter in the same spot is worth one point. Only letters need be considered.
For instance, if the secret string reads 'BLACKBEARD', then 'BEACKBEARD' is worth 9 points, 'WHITEBEARD' is worth 5 points, 'BEARDBLACK' is worth 4 points, and 'CALICOJACK' is worth 1 point.
Compose a function pirate which accepts a string of characters guess and returns the number of characters which match the secret string 'BLACKBEARD'. It should be case-insensitive; that is, you should convert input to upper-case letters. It should return zero for strings which are not ten characters in length.
Your submission should include a function pirate( guess ) which returns a float or int representing the number of matching characters. (You should provide the secret string 'BLACKBEARD' inside the function, not outside of it.)
strings should not have same lengths
Answer:
figure of merit is a quantity used to characterize the performance of a device, system or method, relative to its alternatives. In engineering, figures of merit are often defined for particular materials or devices in order to determine their relative utility for an application.
Following are the Python program to find the string-matching figure:
Python Program:def pirate(g):#defining the method pirate that takes one variable in parameter
if len(g)!= 10:#defining if block that check the parameter length value that is not equal to 10
return 0 #using the return keyword that return a value that is 0
else:#defining else block
g= g.upper()#defining g variable that converts the parameter value into upper value
secretString = "BLACKBEARD"#defining string variable secretString that holds string value
c = 0#defining integer variable c that holds integer value
for i in range(0, len(g)):#defining loop that counts and check value is in string variable
if g[i] == secretString[i]:#defining if block that checks value in secretString variable
c += 1; #defining c variable that increments its value
return c;#using return keyword that return c value
print(pirate("BEACKBEARD"))#using print method that calls pirate method and prints its value
print(pirate("WHITEBEARD"))#using print method that calls pirate method and prints its value
print(pirate("BEARDBLACK"))#using print method that calls pirate method and prints its value
print(pirate("CALICOJACK"))#using print method that calls pirate method and prints its value
Output:

Program Explanation:
Defining the method "pirate" that takes one variable "g" in parameter.Inside the method an if block that checks the parameter length value that is not equal to 10, and uses the return keyword that returns a value that is 0In the else block, define the "g" variable that converts the parameter value into the upper value, and use a string variable "secretString" that holds the string value. In the next step, define an integer variable "c" that holds an integer value, and define a loop that counts and checks the value in a string variable.Inside this, define if block that checks the value in the "secretString" variable, increments the "c" value, and returns the "c" value.Outside the method, a print method that calls the "pirate" method prints its value.Find out more about the string-matching here:

Write a program, TwoDimentionalGrid. Ask the user to enter the size of the 2 dimensional array. Here we are not doing any input validation. We are assuming, user is going to enter a number greater than 1. Create a 2D array with the same row and column number. Now print the array as a number grid starting at 1. Example: At place row number 3 and column number 2, number would be 6 (3*2). Any number would be the product of it's row number and column number. Hint: Use setw 5. Expected Output: Here I am attaching 2 expected output. Make sure your code is running for both input.
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Array size: ");
int n = input.nextInt();
int[][] myarray = new int[n][n];
for(int i =0;i<n;i++){
for(int j =0;j<n;j++){
myarray[i][j] = i * j; } }
for(int i =0;i<n;i++){
for(int j =0;j<n;j++){
System.out.print(myarray[i][j]+" "); }
System.out.println(); }
}}
Explanation:
This prompts the user for the array size
System.out.print("Array size: ");
This gets input for the array size
int n = input.nextInt();
This declares the array
int[][] myarray = new int[n][n];
This iterates through the rows
for(int i =0;i<n;i++){
This iterates through the columns
for(int j =0;j<n;j++){
This populates the array by multiplying the row and column
myarray[i][j] = i * j; } }
This iterates through the rows
for(int i =0;i<n;i++){
This iterates through the columns
for(int j =0;j<n;j++){
This prints each array element
System.out.print(myarray[i][j]+" "); }
This prints a new line at the end of each row
System.out.println(); }
}

Write a program asks the user for an integer N and then adds up the first N odd integers. For example, if the user asks the sum of the first 10 odd integers, the program computes: Use a loop for this. Use instructions and pseudo instructions up to chapter 24. Use exception handler services for input and output. How many odd numbers: 10 The sum: 100 If the user enters a negative integer or non-integer, just print a zero. Start your source file with comments that describe it:
Answer:
The program in Python is as follows:
while True:
try:
num = input("Number of odds: ")
num = int(num)
break
except ValueError:
print("Invalid integer! ...")
sum = 0
odd = 1
if num > 0:
for i in range(num):
sum+=odd
odd+=2
print("Total:",sum)
Explanation:
This is repeated until a valid integer is inputted
while True:
This uses exception
try:
This gets the number of odd numbers
num = input("Number of odds: ")
This converts the input to integer
num = int(num)
break
If input is invalid, this catches the exception
except ValueError:
print("Invalid integer! ...")
This initializes sum to 0
sum = 0
This initializes odd to 1
odd = 1
If input is positive
if num > 0:
This add the first num odd numbers
for i in range(num):
sum+=odd
odd+=2
This prints the total
print("Total:",sum)

In Scheme, source code is data. Every non-atomic expression is written as a Scheme list, so we can write procedures that manipulate other programs just as we write procedures that manipulate lists.
Rewriting programs can be useful: we can write an interpreter that only handles a small core of the language, and then write a procedure that converts other special forms into the core language before a program is passed to the interpreter.
For example, the let special form is equivalent to a call expression that begins with a lambda expression. Both create a new frame extending the current environment and evaluate a body within that new environment. Feel free to revisit Problem 15 as a refresher on how the let form works.
(let ((a 1) (b 2)) (+ a b))
;; Is equivalent to:
((lambda (a b) (+ a b)) 1 2)
These expressions can be represented by the following diagrams:
Let Lambda
let lambda
Use this rule to implement a procedure called let-to-lambda that rewrites all let special forms into lambda expressions. If we quote a let expression and pass it into this procedure, an equivalent lambda expression should be returned: pass it into this procedure:
scm> (let-to-lambda '(let ((a 1) (b 2)) (+ a b)))
((lambda (a b) (+ a b)) 1 2)
scm> (let-to-lambda '(let ((a 1)) (let ((b a)) b)))
((lambda (a) ((lambda (b) b) a)) 1)
In order to handle all programs, let-to-lambda must be aware of Scheme syntax. Since Scheme expressions are recursively nested, let-to-lambda must also be recursive. In fact, the structure of let-to-lambda is somewhat similar to that of scheme_eval--but in Scheme! As a reminder, atoms include numbers, booleans, nil, and symbols. You do not need to consider code that contains quasiquotation for this problem.
(define (let-to-lambda expr)
(cond ((atom? expr) )
((quoted? expr) )
((lambda? expr) )
((define? expr) )
((let? expr) )
(else )))
CODE:
; Returns a function that checks if an expression is the special form FORM
(define (check-special form)
(lambda (expr) (equal? form (car expr))))
(define lambda? (check-special 'lambda))
(define define? (check-special 'define))
(define quoted? (check-special 'quote))
(define let? (check-special 'let))
;; Converts all let special forms in EXPR into equivalent forms using lambda
(define (let-to-lambda expr)
(cond ((atom? expr)

The code can be found in the attached image.
What is the function range?The range() function returns a number series in the range sent as an argument. The returned series is an iterable range-type object and the contained elements will be generated on demand. It is common to use the range() function with the for loop structure. In this way we have that at each cycle the next element of the sequence will be used in such a way that it is possible to start from a point and go incrementing, decrementing x units.
To make it simpler we can write this code as:
a = [[34,38,50,44,39], [42,36,40,43,44], [24,31,46,40,45], [43,47,35,31,26],

Implement the above in c++, you will write a test program named create_and_test_hash.cc . Your programs should run from the terminal like so:
./create_and_test_hash should be "quadratic" for quadratic probing, "linear" for linear probing, and "double" for double hashing. For example, you can write on the terminal:
./create_and_test_hash words.txt query_words.txt quadratic You can use the provided makefile in order to compile and test your code. Resources have been posted on how to use makefiles. For double hashing, the format will be slightly different, namely as follows:
./create_and_test_hash words.txt query_words.txt double The R value should be used in your implementation of the double hashing technique discussed in class and described in the textbook: hash2 (x) = R – (x mod R). Q1. Part 1 (15 points) Modify the code provided, for quadratic and linear probing and test create_and_test_hash. Do NOT write any functionality inside the main() function within create_and_test_hash.cc. Write all functionality inside the testWrapperFunction() within that file. We will be using our own main, directly calling testWrapperFunction().This wrapper function is passed all the command line arguments as you would normally have in a main. You will print the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 2 (20 points) Write code to implement double_hashing.h, and test using create_and_test_hash. This will be a variation on quadratic probing. The difference will lie in the function FindPos(), that has to now provide probes using a different strategy. As the second hash function, use the one discussed in class and found in the textbook hash2 (x) = R – (x mod R). We will test your code with our own R values. Further, please specify which R values you used for testing your program inside your README. Remember to NOT have any functionality inside the main() of create_and_test_hash.cc
You will print the current R value, the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 3 (35 points) Now you are ready to implement a spell checker by using a linear or quadratic or double hashing algorithm. Given a document, your program should output all of the correctly spelled words, labeled as such, and all of the misspelled words. For each misspelled word you should provide a list of candidate corrections from the dictionary, that can be formed by applying one of the following rules to the misspelled word: a) Adding one character in any possible position b) Removing one character from the word c) Swapping adjacent characters in the word Your program should run as follows: ./spell_check
You will be provided with a small document named document1_short.txt, document_1.txt, and a dictionary file with approximately 100k words named wordsEN.txt. As an example, your spell checker should correct the following mistakes. comlete -> complete (case a) deciasion -> decision (case b) lwa -> law (case c)
Correct any word that does not exist in the dictionary file provided, (even if it is correct in the English language). Some hints: 1. Note that the dictionary we provide is a subset of the actual English dictionary, as long as your spell check is logical you will get the grade. For instance, the letter "i" is not in the dictionary and the correction could be "in", "if" or even "hi". This is an acceptable output. 2. Also, if "Editor’s" is corrected to "editors" that is ok. (case B, remove character) 3. We suggest all punctuation at the beginning and end be removed and for all words convert the letters to lower case (for e.g. Hello! is replaced with hello, before the spell checking itself).
Do NOT write any functionality inside the main() function within spell_check.cc. Write all functionality inside the testSpellingWrapper() within that file. We will be using our own main, directly calling testSpellingWrapper(). This wrapper function is passed all the command line arguments as you would normally have in a main
One of your start-ups uses error-correcting codes, which can recover the original message as long as at least 1000 packets are received (not erased). Each packet gets erased independently with probability 0.8. How many packets should you send such that you can recover the message with probability at least 99%
Answer:
Number of packets ≈ 5339
Explanation:
let
X = no of packets that is not erased.
P ( each packet getting erased ) = 0.8
P ( each packet not getting erased ) = 0.2
P ( X ≥ 1000 ) = 0.99
E(x) = n * 0.2

RR * rr
Rr, Rr, Rr, Rr
All the offspring are red and of genotype Rr
F2 Cross
Rr * Rr
RR, Rr, Rr, rr
RR: Rr: rr = 1:2:1
Phenotype ration
red (RR, Rr) : white (rr)
