ByteByteGo: Shift Zeros to the End:

     python
     
   
from typing import List

def shift_zeros_to_the_end(nums: List[int]) -> None:
    j = None

    for i, num in enumerate(nums):
        if num != 0:
            if j is not None:
                assert j < i
                nums[i], nums[j] = nums[j], nums[i]
                j += 1
        else:
            if j is None:
                j = i

Simplified version:

     python
     
   
from typing import List

def shift_zeros_to_the_end(nums: List[int]) -> None:
    j = 0

    for i, num in enumerate(nums):
        if num != 0:
            nums[i], nums[j] = nums[j], nums[i]
            j += 1
