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

你n=b/k;这里没算剩下烟蒂的情况

by Kiloio @ 2021-05-23 13:25:12

比如5 3的情况应该是7，你的程序输出的6

还不如直接推式子

#include<iostream>
using namespace std;
int main(){
    int n,s,k,a;cin>>n>>k;s=n;
    while(s/k!=0){
        a=s/k;
        s%=k;
        n+=a;s+=a;
    }
    cout<<n;
    return 0;
}
