+The [_Treap_][wiki] is a mix between a _Binary Search Tree_ and a _Heap_.
+
+Like a _Binary Search Tree_, it keeps an ordered set of keys in the shape of a
+tree, allowing for binary search traversal.
+
+Like a _Heap_, it associates each node with a priority, making sure that a
+parent's priority is always higher than any of its children.
