Given an array of numbers nums, in which exactly two elements appear only once and all the other elements appear exactly twice. Find the two elements that appear only once.For example:Given nums = [1, 2, 1, 3, 2, 5], return [3, 5].Note:1.The order of…

Given an array of integers, every element appears three times except for one, which appears exactly once. Find that single one.Note:Your algorithm should have a linear runtime complexity. Could you implement it without using extra memory? class Solut…

给定一个整数数组 nums,其中恰好有两个元素只出现一次,其他所有元素均出现两次. 找出只出现一次的那两个元素.示例:给定 nums = [1, 2, 1, 3, 2, 5], 返回 [3, 5].注意:    结果的顺序并不重要,对于上面的例子 [5, 3] 也是正确答案.    你的算法应该具有线性复杂度,你能否仅使用恒定的空间复杂度来实现它?详见:https://leetcode.com/problems/single-number-iii/description/ Java实现: cla…

给定一个整型数组,除了一个元素只出现一次外,其余每个元素都出现了三次.求出那个只出现一次的数.注意:你的算法应该具有线性的时间复杂度.你能否不使用额外的内存来实现?详见:https://leetcode.com/problems/single-number-ii/description/ Java实现: 建立一个32位的数组,来统计每一位上1出现的个数,如果某一位上为1的话,那么如果该整数出现了三次,对3去余为0,把每个数的对应位都加起来对3取余,最终剩下来的那个数就是单独的数字. 参考:htt…

在一个数组中找出两个不同的仅出现一次的数(其他数字出现两次) 同样用亦或来解决(参考编程之美的1.5) 先去取出总亦或值 然后分类,在最后一位出现1的数位上分类成 ans[0]和ans[1] a&(-a)就是计算出这个数,可以参考树状数组. 最后就是注意(nums[i] & a) == 0要加().注意符号运算优先级 class Solution { public: vector<int> singleNumber(vector<int>& nums) {…
