Problem Statement

Write a C program to move all zeros in an array to the end while maintaining the relative order of non-zero elements.

Input Format

First line contains n. Second line contains n elements.

Output Format

Print the modified array separated by spaces.

Constraints

1 <= n <= 100

Sample Input

6
0 1 0 3 12 0

Sample Output

1 3 12 0 0 0

Explanation

Traverse the array, copy non-zero elements sequentially to the front, and fill remaining slots with zeros.

Starter Code

#include <stdio.h>

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        int arr[100];
        for (int i = 0; i < n; i++) {
            scanf("%d", &arr[i]);
        }
        // Write your code here to move zeros to the end
    }
    return 0;
}
