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
代码 /** * @param {number[]} nums * @param {number} target * @return {number[]} */ const twoSum2 = function (nums, target) { const len = nums.length; for (let i = 0; i < len; i++) { for (let j = i + 1; j < len; j++) { if (nums[i] + nums[j] === tar...
