Full Binary Tree

CodeChefOpen on judge ↗

A tree is a connected graph with no cycles. A rooted tree is a tree in which one special vertex is called the root. If there is an edge between **X** and **Y** in a rooted tree, we say that **Y** is a child of **X** if **X** is closer to the root than **Y** (in other words, the shortest path from the root to **X** is shorter than the shortest path from the root to **Y**). A full binary tree is a
