To check if there were duplicate items in the original array, just compare the length of both arrays:const numbers = [1, 2, 3, 2, 4, 5, 5, 6]; const unique = Array.from(new Set(numbers)); if(numbers.length === unique.length) { console.log(`Array doesn't contain duplicates.`...
You must not modify the array (assume the array is read only). You must use only constant, O(1) extra space. Your runtime complexity should be less thanO(n2). There is only one duplicate number in the array, but it could be repeated more than once 非常好的题目,开始是用二分做的,比...
Find the Duplicate Number数组中重复的数 题意:数组中有1+n个数都是1到n之间,找出其中重复的。 解法一:二分搜索,先求出中点mid,然后遍历整个数组,统计所有小于等于mid的数的个数,如果个数小于等于mid,则说明重复值在[mid+1, n]之间,反之,重复值应在[1, mid-1]之间。 解法二:利用快慢指针,思路和带环...

这是一个Java程序,用于解决LeetCode题目中的"Find the Duplicate Number"问题。该程序的主要功能是遍历数组,找出重复的数字并返回其索引。 以下是该程序的代码: public class FindDuplicate { public static int findDuplicate(int[] nums) { int n = nums.length; for (int i = 0; i < n - 1; i++)...
Instead of hoisting package installs in node_modules, install packages in the same manner that they are depended on. This may cause very deep directory structures and duplicate package installs as there is no de-duplicating. Sets --install-strategy=nested....

153. Find Minimum in Rotated Sorted Array Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand. (i.e.,[0,1,2,4,5,6,7]might become[4,5,6,7,0,1,2]). Find the minimum element. You may assume no duplicate exists in the array. ...
