283. Move Zeroes
![][easy]
Problem Statement:
Given an integer array nums
, move all 0's to the end of it while maintaining the relative order of the non-zero elements.
Note that you must do this in-place without making a copy of the array.
Example 1:
Input: nums = [0,1,0,3,12]
Output: [1,3,12,0,0]
Example 2:
Input: nums = [0]
Output: [0]
Constraints:
- 1 <= nums.length <= 104]
- -231] <= nums[i] <= 231] - 1
Follow up: Could you minimize the total number of operations done?
Solution:
java
public class MoveZeroes {
public void moveZeroes(int[] nums) {
int index = 0, end = nums.length;
for (int i = 0; i < end; i++) {
if (nums[i] != 0)
nums[index++] = nums[i];
}
while (index < end)
nums[index++] = 0;
}
}
rs
impl Solution {
pub fn move_zeroes(nums: &mut Vec<i32>) {
let (mut index, mut end) = (0, nums.len());
while index < end {
if nums[index] == 0 {
nums.remove(index);
nums.push(0);
end -= 1;
} else {
index += 1;
}
}
}
}
