C++ Program to Print Matrix in Z form

Last Updated : 07 Aug, 2022

Given a square matrix of order n*n, we need to print elements of the matrix in Z form

Examples:
Input : mat[][] =  {1, 2, 3,
                    4, 5, 6,
                    7, 8, 9}
Output : 1 2 3 5 7 8 9

Input : mat[][] = {5, 19, 8, 7,
                   4, 1, 14, 8,
                   2, 20, 1, 9,
                   1, 2, 55, 4}
Output: 5 19 8 7 14 20 1 2 55 4

CPP

// CPP program to print a square matrix in Z form 
#include <bits/stdc++.h> 
using namespace std; 
const int MAX = 100; 
 
// Function to print a square matrix in Z form 
void printZform(int mat[][MAX], int n) 
{ 
    // print first row 
    for (int i = 0; i < n; i++) 
        cout << mat[0][i] << " "; 
 
    // Print diagonal 
    int i = 1, j = n - 2; 
    while (i < n && j >= 0) // print diagonal 
    { 
        cout << mat[i][j] << " "; 
        i++; 
        j--; 
    } 
 
    // Print last row 
    for (int i = 1; i < n; i++) 
        cout << mat[n - 1][i] << " "; 
} 
 
// Driver function 
int main() 
{ 
    int mat[][MAX] = { { 4, 5, 6, 8 }, 
                    { 1, 2, 3, 1 }, 
                    { 7, 8, 9, 4 }, 
                    { 1, 8, 7, 5 } }; 
    printZform(mat, 4); 
    return 0; 
} 

Output:

4 5 6 8 3 8 1 8 7 5

Time complexity: O(n) for given n*n matrix

Auxiliary Space: O(1)
