#include <bits/stdc++.h>
using i64 = long long;
int main() {
std::ios::sync_with_stdio(false);
std::cin.tie(nullptr);
double A, B, X1, Xn;
int n;
std::cin >> A >> B >> n >> X1 >> Xn;
std::vector<double> f(n);
f[0] = 1;
for (int i = 1; i < n; i++) {
f[i] = f[i - 1] * A + (i >= 2 ? f[i - 2] * B : 0);
}
std::vector<double> X(n);
X[0] = X1;
X[1] = (Xn - X1 * f[n - 1]) / f[n - 2] + X1 * A;
for (int i = 2; i < n; i++) {
X[i] = X[i - 1] * A + X[i - 2] * B;
}
std::cout << std::fixed << std::setprecision(10);
for (int i = 0; i < n; i++) {
std::cout << X[i] << "\n";
}
return 0;
}
这程序好像有点Bug,我给组数据试试?
