首先,需要创建一个函数,它接受两个参数:一个整数数组和一个目标值。该函数将用于查找数组中相加和等于目标值的两个数字。 登录后复制deftwoSum(nums, target): 接下来,需要初始化两个变量登录后复制i和登录后复制j,分别设为 0。这两个变量将用于跟踪数组中相加和等于目标值的两个数字的索引。 登录后复制deftwo...
英文: Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have exactly one solution, and you may not use the same element twice. classSolution(object):deftwoSum(self, nums, target):""":type nu...
解法一:.刚开始看到的的时候,第一个想到的就是用一个嵌套循环把nums列表遍历两次,虽然测试通过了但是耗时实在太长了,然后就考虑了其他时间复杂度低的方法 classSolution:deftwoSum(self,nums,target):""":type nums: List[int]:type target: int:rtype: List[int]"""#用len()方法取得nums列表的长度n=len(...
方法1: 蛮力 蛮力方法很简单。循环遍历每个元素 xx 并查找是否有另一个值等于目标 xtarget−x。 classSolution:deftwoSum(self, nums, target):""" :type nums: List[int] :type target: int :rtype: List[int] """foriinrange(0,len(nums)):forjinrange(i+1,len(nums)):ifnums[i] + nums[j...
