一位过了毒瘤黑题的在求助仅9行代码的红题

by c60521c @ 2020-11-29 22:40:52

AC Code：

using namespace std;
int main()
{
    int n,m;
    scanf("%d %d",&n,&m);
    printf("%d",n+(n-1)/(m-1));
    return 0;
}//要剪掉最后一根烟蒂

数据1： 4 3 5 四个烟，四个烟蒂，3烟蒂换一烟 2： 10 3 14 10烟蒂，换3根，再3烟蒂，再换

看看我这个叭，大佬们```cpp

include<iostream>

using namespace std; int main() { int n, m; cin >> n >> m; if (n < m) { cout << n; return 0; } int sum = 0; sum += n; int s2 = n; while(s2>=m) { int s = s2 / m; sum += s; s2 = n % m; s2 += s; } cout << sum; }
