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.

class Solution:
    def moveZeroes(self, nums: List[int]) -> None:
        j = 0
        for num in nums:
            if num != 0:
                nums[j] = num
                j += 1

        for i in range(j, len(nums)):
            nums[i] = 0
