[2,3] 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...
Given an arraynumscontainingn+ 1 integers where each integer is between 1 andn(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 only). Yo...

You must not 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. 思路: 不能修改数组所以不能排序,不能用额外的空间所以不能用HashMap,考虑鸽巢原理。
