HDU 2085 核反应堆 /* HDU 2085 核反应堆 --- 简单递推 */ #include <cstdio> ; long long a[N], b[N]; //a表示高能质点数目,b表示低能质点数目 int main() { #ifdef _LOCAL freopen("D:\\input.txt", "r", stdin); #endif //质点数目初始化 a[] = ;b[] = ; ; i <= ; ++i){ a[i] =…

看完题,想到用结构体存储高质点和低质点,然后打表存储<33的质点数量. #include<stdio.h> struct hilo { long long hi,lo; }; int main(void) { int i,n,hi,lo; struct hilo narr[35]; narr[0].hi=1; narr[0].lo=0; for(i=1; i<=33; i++) { narr[i].hi=narr[i-1].hi*3+narr[i-1].lo*2; narr[i].…

PS:递推题..  a[n]=a[n-1]*3+2*b[n-1]  b[n]=a[n-1]+b[n-1] 代码: #include "stdio.h" ]; ]; int main(){ int i,c; a[]=; b[]=; ;i<;i++){ a[i]=*a[i-]+*b[i-]; b[i]=b[i-]+a[i-]; } while(~scanf("%d",&c)){ ) ; printf("%lld, %lld\n",a[c…
