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...)...

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...
