python刷leetcode
第一题:给定一个整数数组和一个目标值,找出数组中和为目标值的两个数。
示例:
给定 nums = [2, 7, 11, 15], target = 9 因为 nums[0] + nums[1] = 2 + 7 = 9 所以返回 [0, 1]
class Solution(object): def twoSum(self, nums, target): """ :type nums: List[int] :type target: int :rtype: List[int] """ #result = [] for i in range(len(nums)): for j in range(i+1,len(nums)): sum = nums[i] + nums[j] if sum == target: #result.append(i) #result.append(j) return (i,j)
