题意:给定一个表达式,然后让你求表达式的值. 析:多写几个就会发现规律. 代码如下: #pragma comment(linker, "/STACK:1024000000,1024000000") #include <cstdio> #include <string> #include <cstdlib> #include <cmath> #include <iostream> #include <cstring>…

题意:已知,求A(m, n). 分析:根据样例模拟一下过程就可以找出递推关系. #include<cstdio> #include<cstring> #include<cstdlib> #include<cctype> #include<cmath> #include<iostream> #include<sstream> #include<iterator> #include<algorithm>…

题目:http://acm.hdu.edu.cn/showproblem.php?pid=1165 果断不擅长找规律啊,做这种题静不下心来. Ackermann function can be defined recursively as follows: 递推如上图, 0<m<=3,0<=n<=1000000,,当m==3时,n>=0&&n<=24. 首先发现a(0,i)=i+1; 另外n==0时,a(1,0)=a(0,1)=2; 当m==1,n>…

这个事实上是一个递归题.题目非常easy.m的数非常小.分三种情况.算一下.就能够直接把公式算出来. 当然,也能够用dp做: #include<iostream> #include<string> #include<cstdio> #include<cstring> #include<queue> #include<map> #include<set> #include<vector> #include<…

// Eddy 继续 Problem Description As is known, Ackermann function plays an important role in the sphere of theoretical computer science. However, in the other hand, the dramatic fast increasing pace of the function caused the value of Ackermann function…
