Move Zeroes

Given an array nums, write a function to move all 0's to the end of it while maintaining the relative order of the non-zero elements.

For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0].

Note:

1. You must do this in-place without making a copy of the array.
2. Minimize the total number of operations.

#include <iostream>

#include <vector>

using namespace std;

class Solution {

public:

void moveZeroes(vector<int>& nums) {

int j = 0;

for (int i = 0; i < nums.size(); ++i)

{

if (nums[i] != 0)

nums[j++]=nums[i];

}

for (; j < nums.size(); j++)

nums[j] = 0;

}

};

int main()

{

vector<int> c = { 1, 0, 3, 0, 0, 56 };

Solution A;

A.moveZeroes(c);

for (int i : c)

cout << i << " ";

}
