#include <bits/stdc++.h>
     using namespace std;
     int main(){
         int n,k;
         cin>>n>>k;
         cout<<n+(n-1)/(k-1);
         return 0;
     }

不需要这么麻烦吧？！

#include <bits/stdc++.h>
using namespace std;
int main(){
   int n,k;
   cin>>n>>k;  \\输入
   cout<<n+(n-1)/(k-1); \\n+换来的烟
   return 0;
     }

直接相除向下取整，加上就行。（求关）

@zengyq_2011 我没实力，但我想告诉你：“你的注释斜线方向不对，真正的注释斜线在‘？’这里”

@tangyq_2011 谢谢，确实是错了。但要非要有没实力的人的话那只可能是我hh。

有事的话就私聊吧。
