Java Program to Print Matrix in Z form
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

// Java program to print a // square matrix in Z form import java.lang.*; import java.io.*; class GFG { public static void diag( int arr[][], int n) { int i = 0 , j, k; // print first row for (j = 0 ; j < n - 1 ; j++) { System.out.print(arr[i][j] + " "); } // Print diagonal k = 1 ; for (i = 0 ; i < n - 1 ; i++) { for (j = 0 ; j < n; j++) { if (j == n - k) { System.out.print(arr[i][j] + " "); break ; } } k++; } // Print last row i = n - 1 ; for (j = 0 ; j < n; j++) System.out.print(arr[i][j] + " "); System.out.print("\n"); } public static void main(String[] args) { int a[][] = { { 4 , 5 , 6 , 8 }, { 1 , 2 , 3 , 1 }, { 7 , 8 , 9 , 4 }, { 1 , 8 , 7 , 5 } }; diag(a, 4 ); } } // Code contributed by Mohit Gupta_OMG <(0_o)> |
Output:
4 5 6 8 3 8 1 8 7 5
Time Complexity: O(n*n)
Auxiliary Space: O(1)
