蓝桥杯2022年第十三届省赛真题-刷题统计

解题思路:先把能够算出整数个周期的week算出来，剩下的用求模和除法

注意事项:

参考代码:

#include<stdio.h>

int main()

{

long long int a,b,n,week,number,f=0,sum=0;

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

sum=5*a+2*b;

week=n/sum;

number=n-week*sum;

if(number/a>5)

{

number=number-5*a;

if(number>b)

{

f=7*week+7;

}

else

{

f=7*week+6;

}

}

else

{

if(number%a==0)

f=7*week+(number/a);

else

f=7*week+(number/a)+1;

}

printf("%lld",f);

return 0;

}
