Python Solution

    I don't think I've seen anyone with this solution yet:

    class Solution(object):
        def moveZeroes(self, nums):
            :type nums: List[int]
            :rtype: void Do not return anything, modify nums in-place instead.
            count = 0
            for x in range (0, len(nums)):
                if nums[x] == 0:
                    count += 1
                    nums[x], nums[x-count] = nums[x-count], nums[x]
    • I iterate through the list once, and whenever there is a zero I increment count

    • My count is giving the index of where my next non-zero number should go

    • This places zeros at the end while numbers at the front simultaneously
