My 80ms python code

  • 0
    class Solution(object):
        def removeDuplicates(self, nums):
            if nums == []: return 0
            left = 0
            for i in range(1,len(nums)):
                if nums[i] != nums[left]:
                    if left + 1 < i:
                        nums[left+1] = nums[i]
                    left += 1
            del nums[left+1:]
            return len(nums)

    Look forward to suggestions to remove more duplicated steps. Thanks.
