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.

void moveZeroes(int* nums, int numsSize) {
    int i;
    int count = 0;
    int k = 0;
    for(i = 0; i < numsSize; i++)
    {
        if(nums[i] == 0)
            count++;
    }
    for(i = 0; i < numsSize; i++)
    {
        if(nums[i] != 0)
            nums[k++] = nums[i];
    }
    while(count)
    {
        nums[k++] = 0;
        count--;
    }
}
