代码如下:
#include <iostream> #include <cstdio> #include <cstdlib> #include <cmath> #include <cstring> #include <string> #include <algorithm> #include <vector> #include <set> #include <map> #include <queue> using namespace std; /* freopen("input.txt", "r", stdin); //读数据 freopen("output.txt", "w", stdout); //注释掉此句则输出到控制台 */ int main() { int n,lcm,a,b,c,d,casei=0; int k1,k2,k3; while(cin>>a>>b>>c>>d&&(a+b+c+d)!=-4) { lcm=21252;//lcm(23,28,33); k1=5544;//k1%28=k1%33=0,k1%23=1; k2=14421;//k2%23=k2%33=0,k2%28=1; k3=1288;//k3%28=k3%23=0,k3%33=1; n=(k1*a+k2*b+k3*c-d+lcm)%lcm; if(n==0) n=lcm; printf("Case %d: the next triple peak occurs in %d days.\n",++casei,n); } return 0; }
