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) {
int i=0,j=0;
for(int num:nums){
if(num==0)
i++;
else
nums[j++] = num;
}
for(int k=nums.length-1;k>nums.length-1-i;k--)
nums[k]=0;
}
}
