Move Zeroes to End

Choose one small test case. What result do you expect, and why?

Use the lesson’s examples and explanation to check your idea.

Input

5
0 1 0 3 12

Output

1 3 12 0 0

Sample case — your program reads stdin and prints to stdout.

Starter

Given an array of integers, move all zeroes to the end while maintaining the relative order of non-zero elements.

Use two pointers: one for the position to insert non-zero, one to scan.

Example: [0,1,0,3,12] → [1,3,12,0,0]

Input format Line 1: n. Line 2: n space-separated integers.

Output format The array with zeroes moved to end, space-separated.

Constraints 1 ≤ n ≤ 10⁴
