283\. Move Zeroes

Easy

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:**

*   <code>1 <= nums.length <= 10<sup>4</sup></code>
*   <code>-2<sup>31</sup> <= nums[i] <= 2<sup>31</sup> - 1</code>
