#include<iostream>

#include<vector>
#include<iomanip>
using namespace std;
using LL = long long;
int main(){
#ifdef LOCAL
freopen("data.in", "r", stdin);

#endif
cin.tie(0);
cout.tie(0);
ios::sync_with_stdio(0);
cout << fixed << setprecision(20);
double A, B; int n, x1, xn;
cin >> A >> B >> n >> x1 >> xn;
double c0[20]{}, c1[20]{};
c0[0] = 1;
c1[1] = 1;
for(int i = 2; i <= n; i++){
c0[i] = A * c0[i - 1] + B * c0[i - 2];
c1[i] = A * c1[i - 1] + B * c1[i - 2];
}
double x0 = (xn - c1[n] * x1) / c0[n];
double ans[20]{};
ans[0] = x0;
ans[1] = x1;
for(int i = 2; i <= n; i++){
ans[i] = A * ans[i - 1] + B * ans[i - 2];
}
for(int i = 1; i <= n; i++){
cout << ans[i] << '\n';
}
}
这程序好像有点Bug，我给组数据试试？
