Answer to Question #179761 in Python for ankitha

Question

Write a program to print the anti-diagonal elements in the given matrix.Input

The first line of input will contain an integer N, denoting the number of rows and columns of the input matrix.

The next N following lines will contain N space-separated integers, denoting the elements of each row of the matrix.Output

The output should be a list containing the anti-diagonal elements.Explanation

For example, if the given N is 3, and the given matrix is

1 2 3
4 5 6
7 8 9

The anti diagonal elements of the above matrix are 3, 5, 7. So the output should be the list

[3, 5, 7]

Sample Input 1

3

1 2 3

4 5 6

7 8 9

Sample Output 1

[3, 5, 7]

Sample Input 2

5

44 71 46 2 15

97 21 41 69 18

78 62 77 46 63

16 92 86 21 52

71 90 86 17 96

Sample Output 2

[15, 69, 77, 92, 71]

Answer 1

n = int(input())
a = []
for i in range(n):
    b = list(map(int, input().split()))
    a.append(b[n - 1 - i])
            
print(a)
