+
+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.
+
+[wiki]: https://en.wikipedia.org/wiki/Treap
+
+
+
+## What does it do?
+
+By randomizing the priority value of each key at insertion time, we ensure a
+high likelihood that the tree stays _roughly_ balanced, avoiding degenerating to
+unbalanced O(N) height.
+
+Here's a sample tree created by inserting integers from 0 to 250 into the tree:
+
+{{< graphviz file="treap.gv" />}}
+
+## Implementation
+
+I'll be keeping the theme for this [series] by using Python to implement the
+_Treap_. This leads to somewhat annoying code to handle the rotation process,
+which is easier to do in C using pointers.
+
+[series]: {{< ref "/series/cool-algorithms/" >}}
+
+### Representation
+
+Creating a new `Treap` is easy: the tree starts off empty, waiting for new nodes
+to insert.
+
+Each `Node` must keep track of the `key`, the mapped `value`, and the node's
+`priority` (which is assigned randomly). Finally it must also allow for storing
+two children (`left` and `right`).
+
+```python
+class Node[K, V]:
+ key: K
+ value: V
+ priority: float
+ left: Node[K, V] | None
+ righg: Node[K, V] | None
+
+ def __init__(self, key: K, value: V):
+ # Store key and value, like a normal BST node
+ self.key = key
+ self.value = value
+ # Priority is derived randomly
+ self.priority = random()
+ self.left = None
+ self.right = None
+
+class Treap[K, V]:
+ _root: Node[K, V] | None
+
+ def __init__(self):
+ # The tree starts out empty
+ self._root = None
+```
+
+### Search
+
+Searching the tree is the same as in any other _Binary Search Tree_.
+
+```python
+def get(self, key: K) -> T | None:
+ node = self._root
+ # The usual BST traversal
+ while node is not None:
+ if node.key == key:
+ return node.value
+ elif node.key < key:
+ node = node.right
+ else:
+ node = node.left
+ return None
+```
+
+### Insertion
+
+To insert a new `key` into the tree, we identify which leaf position it should
+be inserted at. We then generate the node's priority, insert it at this
+position, and rotate the node upwards until the heap property is respected.
+
+```python
+type ChildField = Literal["left, right"]
+
+def insert(self, key: K, value: V) -> bool:
+ # Empty treap base-case
+ if self._root is None:
+ self._root = Node(key, value)
+ # Signal that we're not overwriting the value
+ return False
+ # Keep track of the parent chain for rotation after insertion
+ parents = []
+ node = self._root
+ while node is not None:
+ # Insert a pre-existing key
+ if node.key == key:
+ node.value = value
+ return True
+ # Go down the tree, keep track of the path through the tree
+ field = "left" if key < node.key else "right"
+ parents.append((node, field))
+ node = getattr(node, field)
+ # Key wasn't found, we're inserting a new node
+ child = Node(key, value)
+ parent, field = parents[-1]
+ setattr(parent, field, child)
+ # Rotate the new node up until we respect the decreasing priority property
+ self._rotate_up(child, parents)
+ # Key wasn't found, signal that we inserted a new node
+ return False
+
+def _rotate_up(
+ self,
+ node: Node[K, V],
+ parents: list[tuple[Node[K, V], ChildField]],
+) -> None:
+ while parents:
+ parent, field = parents.pop()
+ # If the parent has higher priority, we're done rotating
+ if parent.priority >= node.priority:
+ break
+ # Check for grand-parent/root of tree edge-case
+ if parents:
+ # Update grand-parent to point to the new rotated node
+ grand_parent, field = parents[-1]
+ setattr(grand_parent, field, node)
+ else:
+ # Point the root to the new rotated node
+ self._root = node
+ other_field = "left" if field == "right" else "right"
+ # Rotate the node up
+ setattr(parent, field, getattr(node, other_field))
+ setattr(node, other_field, parent)
+```
