2D Matrix Absolute Difference Diagonals Elements Sum - python

A Square Matrix has N rows and N columns. Get the matrix as input and find the absolute difference between the sum of the values in the two diagonals.

Input Format: The first line contains N. Next N lines containing the elements of the matrix with N column values separated by a space.

Output Format: Absolute difference between the sum of the values in the two diagonals. 

Boundary Conditions: 

• 1 <= N <= 100 

Example Input/Output 1: 

Input: 

2 

35 80 

90 20 

Output:115 

Example Input/Output 2: 

Input:

4 

1 4 4 2 

2 2 1 8 

8 1 3 5 

10 1 8 3 

Output:

5

Coding:

n=int(input())

m=[[int(i) for i in input().split()]for j in range(n)]

s=sum(m[i][i]for i in range(n))

s1=sum(m[i][n-i-1]for i in range(n))

print(abs(s-s1))
