include <iostream>

using namespace std; int main() { int smoke, num; int sum = 0; cin >> smoke >> num; sum += smoke; while (smoke >= num) { smoke = smoke / num; sum += smoke; } cout << sum << endl; }

@huochairenzhishang

只有整除num的烟斗被用来换新的

还有smoke%num个烟头剩余，可下次兑换用

而原代码忽略了这部分烟头

应该改为

while (smoke >= num) {
    int more = smoke / num;
    smoke %= num;
    sum += more;
    smoke += more;
}
