# https://leetcode.cn/problems/two-sum/# 给定一个整数数组 nums 和一个整数目标值 target,请你在该数组中找出 和为目标值 target 的那 两个 整数,并返回它们的数组下标。# 你可以假设每种输入只会对应一个答案。但是,数组中同一个元素在答案里不能重复出现。# 你可以按任意顺序返回答案。from typing import Listclass Solution: def twoSum(self, nums: List[int], target: int) -> List[int]: """ :param nums:数组 :param target:目标值 :return:下标 """ n = len(nums) for i in range(n): for j in range(i + 1, n): if nums[i] + nums[j] == target: return [i, j]if __name__ == '__main__': nums = [2, 7, 11, 15] target = 9 print(Solution().twoSum(nums, target)) nums = [3, 2, 4] target = 6 print(Solution().twoSum(nums, target)) nums = [3, 3] target = 6 print(Solution().twoSum(nums, target))
