LeetCode:287. Find the Duplicate Number LeetCode:287. Find the Duplicate Number 找到数组中重复多次的那个数(唯一)。 思路一:元素值作索引 从位置0开始遍历数组,每次得到的元素值作为下一个遍历的元素,并且将遍历过的元素置为0,如果存在重复的元素值,那么这个位置的元素肯定会被多次访问,如果访问到的元素值...
Find the Duplicate Number Given an array nums containing n + 1 integers where each integer is between 1 and n (inclusive), prove that at least one duplicate number must exist. Assume that there is only one duplicate number, find the duplicate one. Note: You must not modify the array (...

Assume that there is only one duplicate number, find the duplicate one. 即一个包含n+1个整型的数组,数组元素的大小范围是[1,n],说明至少有一个重复的元素。假设只有一个重复元素,找出这个元素。 Example 1: Input: [1,3,4,2,2] Output: 2 Example 2: Input: [3,1,3,4,2] Output: 3 ...
LeetCode 287. Find the Duplicate Number 暴力解法 时间 O(nlog(n)),空间O(n),按题目中Note“只用O(1)的空间”,照理是过不了的,但是可能判题并没有卡空间复杂度,所以也能AC。 双指针判断环 时间O(n),空间O(1),思路十分巧妙,但是使用

Leetcode 287. 寻找重复数 题目 给定一个包含 n + 1 个整数的数组 nums ,其数字都在 1 到 n 之间(包括 1 和 n),可知至少存在一个重复的整数。假设 nums 只有 一个重复的整数 ,找出 这个重复的数 。 来源:力扣(LeetCode) 链接:https://leetcode-cn.com/problems/find-the-duplicate-number 著作权...
Note: 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 than O(n2). There is only one duplicate number in the array, but it could be repeated more than once. ...
