poj1006_Biorhythms

  英语真差劲啊，看题目没看明白，无奈重新开始手抄题目，突然发现一句话 “For each cycle,you will be given the number of days form the beginning of the current year at which one of its peaks occurs. " 看到这句才反应过来应该把前三个值分别取余，好笨啊！

#include <stdio.h>
#include <math.h>
int main(){
    int k,i,n,j;
    int a,b,c,d;
    int cnt=0;
    while(~scanf("%d%d%d%d",&a,&b,&c,&d)){
        if(a==-1&&b==-1&&c==-1&&d==-1)
            break;
        a=a%23;b=b%28;c=c%33;
        for(i=1;i<=1000000;++i){
            if(i<a||i<b||i<c) continue;
            if( ((i-a)%23==0) && ((i-b)%28==0) && ((i-c)%33==0) ){
                if(d>=i){
                    printf("Case %d: the next triple peak occurs in %d days.\n",++cnt,i-d+23*28*33);
                }else 
                    printf("Case %d: the next triple peak occurs in %d days.\n",++cnt,i-d);
                break;
            }
        }
    }
    return 0;
}
