Why do some programmers add chrono::steady_clock:now() in their template
By krazy8, history, 3 years ago, In English

Why do some programmers add rng(chrono::steady_clock::now().time_since_epoch().count()); in their template.
Also why typedef tree<int, null_type, less, rb_tree_tag, tree_order_statistics_node_update> pbds;
Can you also share me best competitive programming template you have ever seen?

The second one is the ordered set included in Policy Based Data Structure You can find more informations here
