283. Move Zeroes

 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?

Soluation:

In Javascript:

var moveZeroes = function(nums) {

    for (let i = nums.length-1; i >= 0; i--) {

        if (nums[i] == 0) {

          nums.splice(i, 1);

          nums.push(0);

      }

    }

    return nums;

};
