Program Code - calculate the absolute difference between the sums of its diagonals.
Given a square matrix, calculate the absolute difference between the sums of its diagonals.
For example, the square matrix is shown below:
1 2 3 4 5 6 9 8 9
The left-to-right diagonal = . The right to left diagonal = . Their absolute difference is .
Complete the function in the editor below.
diagonalDifference takes the following parameter:
- int arr[n][m]: an array of integers
- int: the absolute diagonal difference
The first line contains a single integer, , the number of rows and columns in the square matrix .
Each of the next lines describes a row, , and consists of space-separated integers .
Return the absolute difference between the sums of the matrix's two diagonals as a single integer.
3 11 2 4 4 5 6 10 8 -12
The primary diagonal is:
11 5 -12
Sum across the primary diagonal: 11 + 5 - 12 = 4
The secondary diagonal is:
4 5 10
Sum across the secondary diagonal: 4 + 5 + 10 = 19
Difference: |4 - 19| = 15
Note: |x| is the absolute value of x
Solution Code :-
number = int(input("Enter no of rows:- "))
arr = [[int(input()) for j in range(0,number)] for i in range(0,number)]
