题目大意:和 TOY题意一样,但是需要对隔板从左到右进行排序,要求输出的是升序排列的含有i个玩具的方格数,以及i值. 题目思路:判断叉积,二分遍历 #include<iostream> #include<algorithm> #include<cstring> #include<vector> #include<stdio.h> #include<stdlib.h> #include<queue> #include<…

题目链接:https://cn.vjudge.net/contest/276358#problem/B 题目大意:和上一次写叉积的题目一样,就只是线不是按照顺序给的,是乱序的,然后输出的时候是按照有三个点的区域有多少个---这个类型出发的. AC代码: #include<iostream> #include<cstring> #include<string> #include<cmath> #include<algorithm> #include…
