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...
