Question
![25. Minimum Difference Sum
Given an array of n integers, rearrange them so
that the sum of the absolute differences of all
adjacent elements is minimized. Then, compute the
sum of those absolute differences.
Example
n = 5
arr = [1, 3, 3, 2, 4]
If the list is rearranged as arr' = [1, 2, 3, 3, 4], the
absolute differences are /1-2/ = 1, 12-3|= 1, 13-
3|=0, 13-4/= 1. The sum of those differences is
1+1+0+1 = 3.
Function Description

minDiff has the following parameter:
arr: an integer array
Returns:
int: the sum of the absolute differences of
adjacent elements

- Java Program Your program should use 2D arrays to implement simple matrix operations. Your program should do the following: • Read the number of rows and columns of a matrix M1 from the user. Use an input validation loop to make sure the values are greater than 0. • Read the elements of M1 in row major order • Print M1 to the console; make sure you format as a matirx • Repeat the previous steps for a second matrix M2 • Create a matrix M3 that is the transpose of M1 and print it to the console • Check if M1 and M2 can be added (should have the same dimensions). If possible, add M1 and M2 and print the result to the console. Otherwise print an error message. • Extra credit: Multiply M1 and M2 if possible and print to the console. If the matrices cannot be multiplied, print an error message.

This works straightforwardly if N is even. If N is odd then the final element of B just stores A[N-1] as we can see in the figure below: (added in image) The second array B is now introducing redundancy, which allows us to detect if there has been a hardware failure: in our setup, such a failure will mean the values in the arrays are altered unintentionally. The hope is that if there is an error in A which changes the integer values then the sums in B are no longer correct and the algorithm says there has been an error; if there were an error in B…arrow_forwardHeapsort has heapified an array to: 99 95 67 42 15 40 26 and is about to start the second for loop.
