Arrays

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]

class Solution:
    def moveZeroes(self, nums: List[int]) -> None:
        """
        Do not return anything, modify nums in-place instead.
        """
        z=0
        if len(nums)==1:
            return
        for n in range(len(nums)):
            if nums[z]==0 and nums[n]!=0:
                nums[z],nums[n]=nums[n],nums[z]   
            if nums[z]!=0:
                z+=1
