doubleUp Write a method doubleUp that doubles the size of a list of integers by doubling-up each element in the list. Assume there's enough space in the array to double the size. Suppose a list stores the values [1, 3, 2, 7]. After calling list.doubleUp(), the list should store the values [1, 1, 3, 3, 2, 2, 7, 7].
Answer:
The solution in Python is as follows:
class myClass:
def doubleUp(self,myList):
myList[:0] = myList[::2] = myList[1::2] = myList[:]
mylist = [1, 3, 2, 7]
list = myClass()
list.doubleUp(mylist)
print(mylist)
Explanation:
To create a method in Python, the first step is to create a Class.
This is done in the following line:
class myClass:
Then this line defines the method
def doubleUp(self,myList):
This line duplicates the elements of the list
myList[:0] = myList[::2] = myList[1::2] = myList[:]
This defines the list
mylist = [1, 3, 2, 7]
This creates an instance of the class
list = myClass()
This passes the list to the doubleUp method
list.doubleUp(mylist)
This prints the duplicated list
print(mylist)
The Matlab Script should:1. Clear the command window2. Clear the workspaceQuestion 1: Why do we clear the command window and workspace at the beginning of a script
Answer:
This is done for the simple reason of having more space to work on
Explanation:
This is done for the simple reason of having more space to work on. By clearing the command window and workspace you provide yourself with sufficient space to create new commands without the clutter of the previous commands. This also prevents your focus from shifting towards old commands and allows you to simply focus on the commands you are currently working on. This does not clear all variables from the script, it only clears the current screen but the previous commands can still be accessed by using the up-arrow key

They are both server database.
MySQL Server database has two licensing options namely GPLv2 and Enterprise. Whereas, MariaDB Server database is one that has only one license which it is licensed to namely GPLv2.
Now, the license for both of them differs in that the one for MySQL Server database comes with some available features and support. Whereas, the one for MariaDB comes with the full-featured package.
Ask the user to type in an integer greater than 50 and assign it to a variable called x. Write a program to calculate the sum of squares of positive integers. The loop should stop when the sum is greater than x. At the end of the loop print how many numbers were used to calculate the sum. For example, if x is 100, sum will be 91, and six numbers (1 to 6) were used to calculate sum.
Answer:
The solution in Python is as follows:
num = int(input("Number: "))
if num>50:
sum = 0
count = 0
for i in range(1,num):
count = count + 1
sum = sum + i**2
if sum > num:
sum = sum - i**2
count = count - 1
break;
print("Sum: "+str(sum))
print("Numbers: "+str(count))
else:
print("Number must be greater than 50")
Explanation:
The condition stated in the question do not conform with the example. The question says, the loop should stop when sum > x.
But:
When x = 100 and sum = 91, the program loop should not stop because 91 is not greater than 100.
However, I'll answer based on the example given in the question.
This prompts user for number
num = int(input("Number: "))
The following if condition is executed if number is greater than 50
if num>50:
This initializes sum to 0
sum = 0
This initializes count to 0
count = 0
The iterates through the inputted number (e.g. 100)
for i in range(1,num):
This increases the count
count = count + 1
This calculates the sum of square of the positive integer
sum = sum + i**2
The following removes excess number from the sum
if sum > num:
sum = sum - i**2
count = count - 1
break;
This prints the calculated sum
print("Sum: "+str(sum))
This prints the count of number used
print("Numbers: "+str(count))
The following is executed if user input is less than 50
else:
print("Number must be greater than 50")
Which feature of dart helps in making the code readable,maintainable and finds type error during compile time
Answer:
Sound
Explanation:
Dart is object oriented. It's sound feature helps to make codes more maintainable and readable. The sound type system means that one can never experience w state where where an expression would evaluate to a value that wouldn't match that expressions static type.
The sound system makes the code to be unambiguous. It makes the code to be easier to read as types cannot lie, also your code would be more maintainable since when a piece of code gets to be changed, you would be warned of other pieces that may have gotten broken.
It should be noted that the sound is the feature of dart helps in;
making the code readablemaintainable finds type error during compile time.According to the question, we are to discuss the feature of dart helps in making the code readable and helps in detecting the error as at time if compilation.
As a result of this we can see that sound system makes the code to be unambiguous and it helps in making the code readable.
Therefore, sound is the feature of dart helps in making the code readable.

All of the following are data providers included with .NET for accessing and manipulating data in databases, EXCEPT ____. Group of answer choices
Complete Question:
All of the following are data providers included with .NET for accessing and manipulating data in databases, EXCEPT ____.
Group of answer choices.
A. OLE DB
B. ODBC
C. SQL Server
D. Access
Answer:
D. Access
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
Some examples of data providers included with .NET for accessing and manipulating data in databases are;
A. OLE DB: this is an acronym for Object Linking and Embedding Database. OLE DB was designed and developed by Microsoft corporation and it comprises of various application programming interfaces (APIs) used for data access.
B. ODBC: it is an acronym for Open Database Connectivity and it was designed and developed by Microsoft corporation used for data access through structured query language (SQL).
C. SQL Server: it is a domain-specific language server designed and developed for managing the various data saved in a relational or structured database.
