c++算法学习笔记 (11) 离散化

1.前置知识： unique是 c++标准模板库STL中十分实用的函数之一，使用此函数需要#include <algorithm>头文件该函数的作用是“去除”容器或者数组中相邻元素的重复出现的元素。 (1) 这里的去除并非真正意义的erase，而是将重复的元素放到容器的末尾，返回值是去重之后的尾地址。 (2) unique针对的是相邻元素，所以对于...

作者主页：慢热的陕西人专栏链接：C++算法欢迎各位大佬点赞关注收藏，留言主要讲解了双指针，位运算，离散化以及区间合并。Ⅴ. 双指针是一种利用单调规律将二重循环的时间复杂度降为O(N)的算法；例如：剑指 Offer 48. 最长不含重复字符的子字符串 - 力扣（LeetCode）如果我们用暴力算法的话，肯定是需要O(N)的复杂度，但是我们采用双指针方式可以实现在O(N)的时间复杂度实现代码：int....
