FIND ABSOLUTE DIFFERENCE BETWEEN MAIN AND ANTI DIAGONAL OF MATRIX USING PYTHON
In this tutorial, we will calculate the absolute difference between both diagonal using python
What is a matrix?
A matrix is a rectangular array of numbers or expressions, arranged in rows and columns. A matrix with m rows and n columns is called m x n matrix or m-by-n matrix. i.e. matrix M
3x3
An individual item of a matrix is called element. (i.e. 1 is an element of matrix)
A matrix with single row is called row vector. (i.e. [9 13 5] is a row vector)
A matrix with single column is called column vector. (i.e. [9 1 2] is a column vector)
The main diagonal of a square matrix (where m = n, means number of rows and columns are equal) Mi x j is the list of entries, where i = j.
(main diagonal element of a matrix M is 9, 13, 3)
The anti diagonall of a square matrix Mi x j is the list of entries, where i + j = N (N is number of rows or columns).
(anti diagonal element of matrix M is 5, 11, 2).
Absolute Difference the distance between two numeric values, disregarding whether this is positive or negative. (i.e. absolute difference between 2 and 6 or 6 and 2 is 4.)
n = int(input().strip())arr = []
for _ in range(n): arr.append(list(map(int, input().rstrip().split())))
def diagonalDifference(arr): abs_diff = 0 left_diag = 0 right_diag = 0 k = len(arr) - 1
for i in range(len(arr)): left_diag += arr[i][i] right_diag += arr[i][k] k -= 1 abs_diff = abs(right_diag - left_diag)
return abs_diff
result = diagonalDifference(arr)print(result)
Example:
Input:
3
9 13 51 11 72 6 3 Output:5
