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,思路和带环链...
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 the array is read o...
这道题给了我们一个数组,数组中的数字可能出现一次或两次,让我们找出所有出现两次的数字,由于之前做过一道类似的题目Find the Duplicate Number,所以不是完全无从下手。这类问题的一个重要条件就是1 ≤ a[i] ≤ n (n = size of array),不然很难在O(1)空间和O(n)时间内完成。首先来看一种正负替换的方法...
