Move Zeroes

質問する

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

初めての試み

var moveZeroes = function (nums) {
    for (let i = 0; i < nums.length; i++) {
        if (nums[i] === 0) {
            nums.splice(i, 1);
            nums.push(0);
        }
      i--
    }
    return nums;
 };

            nums.splice(i, 1);
            nums.push(0);
