Can you solve this real interview question? Find All Duplicates in an Array - Given an integer array nums of length n where all the integers of nums are in the range [1, n] and each integer appears at most twice, return an array of all the integers that
Find All Duplicates in an Array 442. Find All Duplicates in an Array Given an array of integers, 1 ≤ a[i] ≤ n (n = size of array), some elements appear twice and others appear once. Find all the e...[leetcode] 442. Find All Duplicates in an Array 样例: Input: Output: ...
与[LeetCode]Find All Numbers Disappeared in an Array几乎一样,不同之处就是找出twice的数。那么我们只要当nums[i]!=i+1时,然后又当nums[nums[i]-1]==nums[i]时,把nums[i]放入set即可。
leetcode之Find All Numbers Disappeared in an Array 本文主要解析《Find All Numbers Disappeared in an Array》,顺便简单解释一下《Find All Duplicates in an Array》。 该题的含义是:给定一个长度为n的数组,数组元素是1~n。但是有些元素出现一次,有些元素出现两次,从而也会导致有些元素不出现。现在让我们...
