题目: 448. Find All Numbers Disappeared in an Array 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…

problem 645. Set Mismatch 题意: solution1: 统计每个数字出现的次数了,然后再遍历次数数组,如果某个数字出现了两次就是重复数,如果出现了0次,就是缺失数. 注意:如何统计每个数字出现的次数: class Solution { public: vector<int> findErrorNums(vector<int>& nums) { vector<, ), cnt(nums.size(), ); ]; ; i<nums.siz…

Question 645. Set Mismatch Solution 思路: 遍历每个数字,然后将其应该出现的位置上的数字变为其相反数,这样如果我们再变为其相反数之前已经成负数了,说明该数字是重复数,将其将入结果res中,然后再遍历原数组,如果某个位置上的数字为正数,说明该位置对应的数字没有出现过,加入res中即可 Java实现: public int[] findErrorNums(int[] nums) { /* int a = 0; for (int i : nums) { if (nu…
