#include <bits/stdc++.h>
using namespace std;
using ll = long long;
using ld = long double;
#define rep(i, a, b) for(ll i = a; i < (b); i++)
int main() {
ld A, B;
ll N;
ld X0, Xl;
cin >> A >> B >> N >> X0 >> Xl;
vector<ld> C(N), D(N);
C[0] = D[0] = X0;
D[1] = 1;
rep(i, 2, N) {
C[i] = C[i - 1] * A + C[i - 2] * B;
D[i] = D[i - 1] * A + D[i - 2] * B;
}
// Xl == C.back() * (1 - p) + D.back() * p;
ld p = (Xl - C.back()) / (D.back() - C.back());
cout.precision(12);
rep(i, 0, N) {
cout << lerp(C[i], D[i], p) << '\n';
}
}
这程序好像有点Bug，我给组数据试试？
