在JS中比较优雅的方式是利用JS的对象作为hash的方式: 1vartwoSum =function(nums, target) {2varhash ={};3vari;4for(vari = 0; i < nums.length; i++) {5if(typeofhash[nums[i]] !== "undefined") {6return[i, hash[nums[i]]];7}8hash[target - nums[i]] =i;9}10}; 这里面还可以...

我觉得 Two Sum 系列问题就是想教我们如何使用哈希表处理问题。我们接着往后看。 TwoSum II 稍微修改一下上面的问题,要求我们设计一个类,拥有两个API: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 classTwoSum{// 向数据结构中添加一个数 numberpublicvoidadd(int number);// 寻找当前数据结构中是否存...

1. Two Sum Description 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. Example: Given nums = [2, 7, 11, 15], targ...
