我用周期取整方法做的就是算出满足日期一致的条件下三个周期的个数同时为整数时的最早日期,再同当前日期进行对比处理得出答案。 #include<stdio.h> int main() { float a,b,c,x,y,z; int days,data,ty,tz,i=0; while(true) { scanf("%f%f%f%d",&a,&b,&c,&data); if(a==-1&&b==-1&&c==-1&&data==-1)break; i++; a=int(a)%23;b=int(b)%28;c=int(c)%33; for(x=0.0;;x++) { y=(a-b+23*x)/28; z=(a-c+23*x)/33; ty=int(y); tz=int(z); y-=ty; z-=tz; if(y==0.0&&z==0.0)break; } if(a+23*x-data<0) days=int(a+23*x+21252-data); else if(a+23*x-data>0) days=int(a+23*x-data); else days=21252; printf("Case %d: the next triple peak occurs in %d days.\n",i,days); } return 0; } Followed by: Post your reply here: |
