这是今天xd弄的一个专题,,,,很是坑爹,,,c++过了,但是g++就是过不了,,,让我纠结了半个多小时,,,悲催,,, prim算法: #include<iostream>#include<string.h>#define N 505#define M 99999999#define FOR(i,s,t) for(int i=(s);i<=(t);++i)using na
找到递推公式f(n)=2*f(n-2)+f(n-1)+1; 要想卸下前n个环,要卸先下前n-2个,然后卸下第n个环,然后按上n-2个环,在卸下n-1环。。。。 AC代码: #include<iostream>#include<cstdio>#include<string.h>#include<algorithm>#define M 200907using namespace s
