(Algebra: perfect square
)
Write a program that prompts the user to enter an integer
m
and find the smallest integer
n
such that
m * n
is a perfect square.
(Hint: Store all smallest factors of
m
into an array list.
n
is the product of the factors that appear an odd number of times in the array list.
For example, consider
m
= 90, store the factors 2, 3, 3, 5 in an array list. 2 and 5 appear an odd number of times in the array list. So,
n
is 10.)
Sample Run 1
Enter an integer m: 1500
The smallest number n for m x n to be a perfect square is 15
m x n is 22500
Sample Run 2
Enter an integer m: 63
The smallest number n for m x n to be a perfect square is 7
m x n is 441

//the try catch block below is for trapping error with the input try {…
(Average the major diagonal in a matrix) Write a method that averages all the numbers in the major diagonal in an n * n matrix of double values using the following header:
public static double averageMajorDiagonal(double[][] m)
Write a test program that reads a 4-by-4 matrix and displays the average of all its elements on the major diagonal. Here is a sample run:
1 2 3 4.0
5 6.5 7 8
9 10 11 12
13 14 15 16
Average of the elements in the major diagonal is 8.625
Write method body of followingfunction:
void deleteRange(int from, int to){
}
Above function deletes whole range of elements from an array by asking user for starting value and ending value. (Dont use pointers)
Write best solution for worst case scenario.

- please code in python Forbidden concepts: arrays/lists (data structures), recursion, custom classes You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen.The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: (refer image1 ) Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character.

- Shift Right k Cells (Use Python) Consider an array named source. Write a method/function named shifRight( source, k) that shifts all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftRight(source,3) After calling shiftRight(source,3), printing the array should give the output as: [ 0,0,0,10,20,30 ]arrow_forward(See attached photo) Please explain the exact running time of the program.
