Move Zeros

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 = 0, j = 0; for(i = 0; i < numsSize; i++){ //copy non-zero elements if(nums[i] != 0){ nums[j] = nums[i]; j++; } } //put zeros in the end while(j < numsSize){ nums[j++] = 0; } }
