Using subtrees as subproblems. However, regular binary search trees suffer from imbalancing, which causes the tree to have up to an O (n) O(n) depth and blows up the time complexity. txt) or read online for free.

A treap is a data structure which combines binary tree and binary heap (hence the name: tree + heap ⇒ Treap). In problems where the query range is at most something like 10 6 106, a normal segment tree suffices. Like a regular binary search tree, treaps contain keys that can be inserted, erased, and searched for in Θ (log n) Θ(logn).
