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.
思路简单:
遍历nums,把所有非零元素填到前面,后面的补零。
class Solution {
public void moveZeroes(int[] nums) {
int j=0;
for(int i=0;i<nums.length;i++){
if(nums[i]!=0)
nums[j++] = nums[i];
}
for(;j<nums.length;j++){
nums[j] = 0;
}
}
}
