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:
You must do this
in-place without making a copy of the array.
Minimize the total number of operations.
public class Solution {
public void moveZeroes(int[] nums) {
if(nums.length==0) return;
int j=0;
for(int i=0;i<nums.length;i++){
if(nums[i]!=0){
nums[j++]=nums[i];
}
}
while(j<nums.length){
nums[j++]=0;
}
}
}
