#include<bits/stdc++.h>
using namespace std;
typedef long double lf;
const lf Pi=acos(-1);

return (lf)x;
}
lf solve(){

lf x2=(r+a)/cos(d)+(b-(r+a)*tan(d))*sin(d);
if(d<Pi/2&&b-(r+a)*tan(d)>0)return min(x1,x2)-r;
return x1-r;
}
signed main(){
int T;
cin>>T;
while(T--)cout<<fixed<<setprecision(15)<<solve()<<"\n";
return 0;
}
这程序好像有点Bug，我给组数据试试？
