Solution: Average of Levels in Binary Tree

Explore how to calculate the average value of nodes at each level of a binary tree using breadth-first search. This lesson guides you through implementing a queue to traverse levels, summing node values, and computing averages efficiently in C++. Understand the approach, code structure, and time-space complexity for practical tree traversal and manipulation.

Statement

You are given the root of a binary tree. Your task is to return the average value of the nodes on each level in the form of an array.

Note: Only answers within 10510^{-5} of the actual answer will be accepted.

Constraints:

  • The number of nodes in the tree is in the range [1,104][1, 10^4] ...
