Problem - 3805 题意是给出边的长度的,求出边长相等的三角形,输出任意一种答案.边长是1~n的数,每个只能用一次. 其实比较容易可以看出,无论我们怎么操作,只要保持边长总和都是相邻整数就是了.例如现在得到长度为n,n+1,n+2的三条边,可以对应加上m+2,m+0,m+1,从而变成了s+1,s+0,s+2.反正我们在处理123之前,保持着总和是这样的结构就行了.然后最后到了123的时候就能对应加上去,使之相等. 代码如下: #include <cstdio> #include &l…

6300.Triangle Partition 这个题就是输出组成三角形的点的下标. 因为任意三点不共线,所以任意三点就可以组成三角形,直接排个序然后输出就可以了. 讲道理,没看懂官方题解说的啥... 官方题解: 求个凸包,然后选择凸包一条边AB,然后找个和AB夹角最小的点C,把ABC当做一个三角形删掉即可.这样做个n次,显然这样求出来的三角形们是合法的. 代码: //1003-6300-三角形水题 #include<iostream> #include<cstdio> #incl…
