283. 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:
- 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 j=1;
for (int i = 0; i < nums.length; i++) {
if (nums[i] != 0)
continue;
else {
while (i+j <nums.length && nums[i+j]==0) j++;
if (i+j ==nums.length) break;
nums[i]= nums[i+j];
nums[i+j]=0;
}
}
}
