# -*- coding:utf-8 -*-

class Solution(object):
    def removeElement(self, nums, val):
        """
        :type nums: List[int]
        :type val: int
        :rtype: int
        """
        for i in range(len(nums) - 1, -1, -1):
            if nums[i] == val:
                nums.pop(i)
        return len(nums)
if __name__ == '__main__':
    nums = [3, 2, 2, 3]
    print(Solution().removeElement(nums, 3))

思路：做过前面0026这道题就很好做了，倒序的理由也一样，只不过判断条件稍微改变。
