LeetCode题解之Find All Numbers Disappeared in an Array

1、题目描述

2.问题分析

使的 A[i] = i+1 ,最后检查不满足这个条件的i+1 .即为缺失的值。

3.代码

 1 vector<int> findDisappearedNumbers(vector<int>& nums) {
 2         for( int i = 0; i < nums.size() ; ++i ){
 3             if( nums[i]  != nums[ nums[i] - 1 ] ){
 4                 swap( nums[i] , nums[nums[i] - 1] );
 5                 i--;
 6             }
 7         }
 8         vector<int> result ;
 9         for( int i = 0; i < nums.size() ; i++){
10             if( nums[i] != i+1 )
11                 result.push_back( i+1 );
12         }
13         return result ;
14     }

LeetCode 448 Find All Numbers Disappeared in an Array 解题报告

题目要求 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) run

算法(2) Find All Numbers Disappeared in an Array

题目:整数数组满足1<=a[i]<=n(n是数组的长度),某些元素出现一次,某些元素出现两次,在数组a[i]中找到[1,n]区间中未出现的数字.比如输入[4,3,2,7,8,2,3,1],输出[5,6].时间复杂度要求是O(n),空间复杂度要求O(1) 思路:看许多网友说用set数据结构去做,这就违反了空间复杂度的要求,所以排序还是要本地做的.遍历数组,把这个数字放到它该待的地方:比如a[0]=4,那么我们就把4放到a[3]处,然后把a[3]处的7放到a[6]处,把a[6]处3放在a[2]处,
