用减法，慢慢来。

@lcf3241142097 小心边缘数据

这个是w#3的代码

#include<cstdio>
using namespace std;
int main()
{
    int n,k,count,countt;
    scanf("%d%d",&n,&k);
    count=n;
    countt=n;
    while(countt>k)
    {
        countt-=k;
        countt++;
        count++;
    }
    printf("%d",count);
    return 0;
}
countt>k改成countt>=k就A了
