Answer to Question #165085 in Python for teja

Question

Anti-Diagonals

Given a MxN matrix,write a program to print all Anti-Diagonals elements of matrix

Input

The first line of input will contain a M, N values separated by space.

The second line will contain matrix A of dimensions MxN.

Output

The output should contain anti-diagonal elements separated by a line.

Explanation

For example, if M = 2, N = 3

input

1 5 5

2 7 8

output:

1

5 2

5 7

8

Answer 1

#!/usr/bin/env python

# read matrix dimentions
l = input().split()
m = int(l[0])
n = int(l[1])

# read a matrix
A = []
for i in range(m):
    row = []
    l = input().split()
    for j in range(n):
        row.append(float(l[j]))
    A.append(row)

# print antidiagonal
j = n-1
for i in range(m):
    print(A[i][j])
    j -= 1
    if j < 0:
        break
