刷题统计————小白思路

解题思路:
先求出做完题需要用几整数周，再判断出剩余的题数能否在周一到周五做完，最后将整周数*7加上剩余的天数得出总天数
注意事项:

参考代码:

#include<stdio.h>

int main()

{

long a,b,n,weeks,days,sum=0,remainder;    //weeks是周数，days是做完剩余的题不够一周的天数 

                                                                     //remainder是剩余的题数 

scanf("%ld%ld%ld",&a,&b,&n);

weeks=n/(5*a+2*b);                                   //求出需要用的整周数 

remainder=n%(5*a+2*b);                          //求出剩余的题数 

if(remainder<=(5*a))                                 //如果剩余的题数能够在周一到周五做完 

{

if(remainder%a==0)                                 //如果剩余的题数能够在整天做完 

days=remainder/a;

else                                                           //如果剩余的题数不够一整天做的

days=remainder/a+1;    

}

else                                                           //如果剩余的题周一到周五做不完 

{

if((remainder-5*a)%b==0)                       //如果整天做完 

days=(remainder-5*a)/b+5;

else                                                           //如果整天做不完。 

days=(remainder-5*a)/b+6;

}

sum=weeks*7+days;

printf("%ld\n",sum);

return 0;

}
