在CareerCup中有一道类似的题,5.7 Find Missing Integer 查找丢失的数,但是那道题不让我们直接访问整个int数字,而是只能访问其二进制表示数中的某一位,强行让我们使用位操作Bit Manipulation来解题,也是蛮有意思的一道题。 LeetCode All in One 题目讲解汇总(持续更新中...)...

今天介绍的是LeetCode算法题中Easy级别的第65题(顺位题号是268)。给定一个包含n个不同数字的数组,取自0,1,2,...,n,找到数组中缺少的数字。例如: 输入:[3,0,1] 输出:2 输入:[9,6,4,2,3,5,7,0,1] 输出:8 注意:您的算法应该以线性运行时复杂性运行。 你能用恒定的额外空间复杂度来实现吗?
这就是 LeetCode 136 - Single Number 这题,所以我们可以采用相同的异或解法。 因为a ^ a = 0 ,所以出现两次的数异或后会相互抵消。 那么求所有数的异或和即可,最后剩余的就是只出现一次的数。 时间复杂度:O(n) 需要遍历处理全部 O(n) 个数 空间复杂度:O(1) 只需要维护常数个额外变量即可 代码(Python...
