Python Program to Print Matrix in Z form

Python Server Side Programming Programming

In this article, we will learn about the solution and approach to solve the given problem statement.

Problem statement −Given a square matrix of order n*n, we need to display elements of the matrix in Z form.

Z form is traversing the matrix in the following steps −

Traverse the first row
Now, traverse the second principal diagonal
Finally, traverse the last row.

We will take an input matrix here implicitly taken to demonstrate the flow of code.demostrate

Example

arr = [[1, 2, 6, 9],
   [1, 2, 3, 1],
   [7, 1, 3, 5],
   [1, 8, 7, 5]]

n = len(arr[0])
i = 0
for j in range(0, n-1):
   print(arr[i][j], end = ' ')
k = 1
for i in range(0, n):
   for j in range(n, 0, -1):
      if(j == n-k):
         print(arr[i][j], end = ' ')
         break;
   k+= 1
# Print last row
i = n-1;
for j in range(0, n):
   print(arr[i][j], end = ' ')

Output

1 2 6 9 3 1 1 8 7 5

All variables and functions are declared in global scope as shown in the figure below.

Conclusion

In this article, we learned about the approach to Print Matrix in Z form.
