Note: ***(Every labeled tree of N nodes can be uniquely represented as an array of N−2 integers and vice versa). ***(Number of unique tree constructed by N vertex= N^(N-2) According to prufer code).

Practice:
To generate random Tree: 1. use template of prufer code. 2.
n=vertex_number;
cout<<n<<'\n';
vector <int> pruf(n-2);
for(auto &x : pruf) x = gen_random(1, n);
vector<pair<int,int>> edge = pruferCodeToTree(pruf);
for(auto &e : edge) cout << e.uu << " " << e.vv << '\n';mt19937_64 rng(chrono::steady_clock::now().time_since_epoch().count());
inline ll gen_random(ll l, ll r) {
return uniform_int_distribution<ll>(l, r)(rng);
}
// call for get a random number (from l to r range): gen_random(l,r);for((i = 1; ; ++i)); do
