买房子

题目有点坑，收入是年初更新、房价是年尾更新
#include<iostream>
using namespace std;
int TryBuy(int n,int k){
float price = 200;
float income = n;
float money = 0;
for(int i=1;i<=21;i++){
money+=income;
if(money>=price) return i;
price*=(1+(float)k/100);
}
return 0;
}
int main(){
int n,k;
while(cin>>n>>k){
int year = TryBuy(n,k);
if(year>0){
cout<<year<<endl;
} else {
cout<<"Impossible"<<endl;
}
}
return 0;
}
