【LEETCODE】283-Move Zeroes

Given an array nums, write a function to move all0's to the end of it while maintaining the relative order of the non-zero elements.

For example, given nums = [0, 1, 0, 3, 12], after calling your function,nums should be [1, 3, 12, 0, 0].

Note:

1. You must do this in-place without making a copy of the array.
2. Minimize the total number of operations.

"""                a=b=0                for b in range(len(nums)):            if nums[b]!=0:                t=nums[a]                nums[a]=nums[b]                nums[b]=t                a+=1        #return nums
