Contains Duplicate Given an array of integers, find if the array contains any duplicates. Your function should return true if any value appears at least twice in the array, and it should return false if every element is distinct. 题意给定一个数组,查找数组是否存在重复项。 解决方法很多,hash表...
一、Contains Duplicate Given an array of integers, find if the array contains any duplicates. Your function should return true if any value appears at least twice in the array, and it should return false if every element is distinct. 分析:先把数组排个序,然后遍历排序后的数组,查看相邻元素是否...
Can you solve this real interview question? Contains Duplicate - Given an integer array nums, return true if any value appears at least twice in the array, and return false if every element is distinct. Example 1: Input: nums = [1,2,3,1] Output: tr
var containsDuplicate = function(nums) { var hash = {} for(var i = 0; i < nums.length; i++){ var el = nums[i]; if(el in hash){ return true } hash[el] = true } return false }; 第218题,判定数组里面有重复项,并要求它们的索引值的绝对值不能大于 k, 因此我们需要将之前索引...
