Task is to have a function which takes an array. Then removes elements from the array which are contained more then one time. Finally returns an array with only unique elements.
Here's my solution:

let withDuplicates = [1, 2,...

So I'm searching my binary search tree of Vehicle objects and I'm just wondering whether there would be much point/is it best practice to search if a node has a left/right child first like so -

Or just go with the foillowing, since it will retu...
Let's say the following code.

I've been trying to implement a persistent treap (everything is fine with it) and I decided to use std::shared_ptr for getting rid of unused nodes. Don't be scared if you don't know about persistent treaps, treat is as a binary search tree.
Here is my code:

This gets close but it varies from top too often.
The key weakness, I believe, is counting the sleepers.
How can it be made more accurate?
