Move Zeroes
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) -> None:
slow = 0
for fast in range(len(nums)):
if nums[fast] != 0 and nums[slow] == 0:
nums[slow], nums[fast] = nums[fast], nums[slow]
# wait while we find a non-zero element to
# swap with you
if nums[slow] != 0:
slow += 1
