Print Matrix in zig-zag order
“Print Matrix in zig-zag order” is a a problem of printing the given matrix of size N*M in zig-zag order.
The zig-zag order of the matrix is traversing the first row of matrix from left to right, next row from right to left, next row from left to right and so on.
Print Matrix in Zig-Zag Order
Example:
Input: 1 2 3 4 5 6 7 8 9 OUTPUT: 1 2 3 6 5 4 7 8 9
C++ Program to Print matrix in Zig-Zag Order is as follows:
/* Program to Print matrix in Zig-Zag Order */
#include<bits/stdc++.h>
using namespace std;
int main()
{
int N,M;
// Scan Dimensions of the matrix
cout<<"Enter the dimension of the matrix:\n";
cin>>N>>M;
int matrix[N][M];
// Scan Matrix Elements
cout<<"Enter the elements of the matrix:\n";
for(int i = 0 ; i < N ; i++)
for(int j = 0 ; j < M ; j++)
cin>>matrix[i][j];
// Print the matrix in Zig-Zag Order
cout<<"The Zig-zag traversal of the matrix is:\n";
for(int i = 0 ; i < N ; i++)
{
if(i%2==0)
{
for(int j = 0 ; j < M ; j++)
cout<<matrix[i][j]<<" ";
}
else
{
for(int j = M-1 ; j>=0 ; j--)
cout<<matrix[i][j]<<" ";
}
}
}
OUTPUT: Enter the dimension of the matrix: 3 3 Enter the elements of the matrix: 1 2 3 4 5 6 7 8 9 The Zig-zag traversal of the matrix is: 1 2 3 6 5 4 7 8 9
