题面 单调栈模板题. 单调栈与单调队列一样,都是维护了一段区间内的顺序. 然后--这个题用一个栈维护一下贪心就没了. 具体参考这一篇题解 #include <bits/stdc++.h> #define itn int #define gI gi using namespace std; inline int gi() { int f = 1, x = 0; char c = getchar(); while (c < '0' || c > '9') {if (c == '-')…
因为涉及到对模板的理解,所以就着代码看会好一些. 让那些坚决不颓代码的人受委屈了. 我是对着wzz的板子默写的,可能不完全一样啊. 还有代码注释里都是我个人的理解,不保证正确,但欢迎指正. 可以有选择的浏览,单调栈的那个非模板部分可以不看,自己想. 因为写的稍微有点详细所以在网页上极丑,粘到自己gedit上看吧. #include<cstdio> #include<algorithm> #define int long long ]; ],y[],sa[],rk[],l=,c[],…
