这就是 LeetCode 136 - Single Number | 只出现一次的数字 (Rust) 题目。 完全是考察异或的特性 a ^ a = 0 ,这样最后只有出现奇数次的字母会留下来。 (当然本题也可以使用加减法抵消,获得类似的结果,因为数据范围比较小,不过对于 136 这题就只能使用异或了) 时间复杂度:O(n) 空间复杂度:O(1) 代码 im...
数组可能是单调递增,也可能有一个变换。 (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2) 要求找出最小的数。 二、 分析 这道题正如题目所说的分来两种情况 1、 严格单调递增 2、 有一个拐点 我们须要分情况处理。当然也能够无论这些直接遍历,即从头到尾扫描,找出最小的数;假设依据题意,...
