Given an array of integers where 1 ≤ a[i] ≤n(n= size of array), some elements appear twice and others appear once. Find all the elements of [1,n] inclusive that do not appear in this array. Could you do it without extra space and in O(n) runtime? You may assume the returne...

448. Find All Numbers Disappeared in an Array 448. Find All Numbers Disappeared in an Array 解法一:空间复杂度O(n)。思路:借助一个数组记录下某一数数否出现过。 思路:考虑到数组中数字的范围是1-n,可以看成是数组的index索引,改变所有出现的索引对应的数组的数值,然后判断那些仍未被改变。 下面第一...
这道题让我们找出数组中所有消失的数,跟之前那道Find the Duplicate Number极其类似,那道题让找出所有重复的数字,这道题让找不存在的数,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。三种解法也跟之前题目的解法极其类似。首先来看第一种解法...
