#include<bits/stdc++.h>
using namespace std;
const int N=49;
int n;
double a,b,x[N],y[N];
signed main(){
ios_base::sync_with_stdio(0),cin.tie(0);
double lst;
cin >> a >> b >> n >> x[0] >> lst;
y[1]=1;
for(int i=2; i<n; ++i){
x[i]=a*x[i-1]+b*x[i-2];
y[i]=a*y[i-1]+b*y[i-2];
}
x[1]=(lst-x[n-1])/y[n-1];
for(int i=2; i<n; ++i){
x[i]=a*x[i-1]+b*x[i-2];
}
cout << fixed << setprecision(20);
for(int i=0; i<n; ++i) cout << x[i] << "\n";
}
这程序好像有点Bug，我给组数据试试？
