Problem statement

Given an integer array nums, move every zero to the end while preserving the relative order of all nonzero values. Return the transformed array.

The returned-array interface represents the standard in-place task for portable execution.

Function

moveZeroes(nums: int[]) → int[]

Examples

Example 1

nums = [0,1,0,3,12]return = [1,3,12,0,0]

The nonzero values remain in their original order and both zeroes move to the suffix.

Example 2

nums = [0]return = [0]

A one-zero array is unchanged.

Constraints

0 <= nums.length <= 10^5.
Each value is a signed 32-bit integer.
