http://poj.org/problem?id=1995 简单的快速幂问题 要注意num每次加过以后也要取余,否则会出问题 #include<iostream> #include<cstdio> using namespace std; typedef long long ll; ll mod_pow(ll x,ll n,ll mod) { ll res=; ) { ) res=res*x%mod; x=x*x%mod; n>>=; } return res; }…

题意:给出A1,…,AH,B1,…,BH以及M,求(A1^B1+A2^B2+ … +AH^BH)mod M. 思路:快速幂 实例 3^11  11=2^0+2^1+2^3    => 3^1*3^2*3^8=3^11 实现代码: int solve(int a,int b) { int ans=1;          while(b){ if(b&1)  ans=ans*a;   a=a*a;  b>>=1;} } 解释一下代码:b&1即二进制表达式的最后一位,  11二…
