Write a code to find either the sum above or
below the main diagonal of an n by n matrix MAT
of integer values. The main diagonal represents
all the elements denoted by MAT[x][x] where x is
the values between 0 and n-1. First, the program
asks the user to enter the size of the matrix n.
Then the user should enter 0 to either find the
sum of the elements in the region above the
diagonal or 1 to find the sum of the elements
under the diagonal. Finally, the user has to insert
the n*n elements of the matrix in a row order
where the elements of the first row will be
inserted first and then the second row and so on.
The output simply represents the desired sum
value.
IMPORTANT NOTES:
• If the matrix size < 0, the output will be
"Negative input".
• If the matrix size = 0, the output will be "Zero
size matrix".
• If the user input for the desired region is not 0
or 1 then the output will be "Wrong entry".
• The user will not be given the chance to enter
the matrix values if any of the previous
conditions occured.
I/O
Program Input:
• Array size (n)
• Desired region(0 or 1)
• n*n integer elements
Program Output:
• A single line that shows the desired
sum value
Sample Testcase 0:
Input:
(-2)
Output:
Negative input
Sample Testcase 1:
Input:
0
Output:
