P1150 Peter 的烟

我Peter的烟这题总是90分(第三个点过不去),大家帮我找找错。代码如下:

#include<cstdio>
#include<iostream>
using namespace std;
int main()
{
    int n,k,ans=0;
    scanf("%d%d",&n,&k);
    ans+=n;
    while(n>=k)
    {
        n/=k;
        ans+=n;
    }
    printf("%d",ans);
    return 0;
}

程序应为:

#include<cstdio>
#include<iostream>
using namespace std;
int main()
{
    int n,k,ans=0;
    scanf("%d%d",&n,&k);
    ans+=n;
    while(n>=k)
    {
        ans=ans+n/k;
        n=n/k+n%k;
    }
    printf("%d",ans);
    return 0;
}
错因:每一次用烟蒂换烟,可以换n/k根烟,但还有n%k个烟蒂不能丢,之后可能会有用
