// 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.

//

//

//

// Credits:Special thanks to @jianchao.li.fighter for adding this problem and creating all test cases.

/**

* @param {number[]} nums

* @return {void} Do not return anything, modify nums in-place instead.
