Solution: Average of Levels in Binary Tree

Explore how to calculate the average value of nodes at each level in a binary tree by applying breadth-first search techniques. This lesson guides you through a level-by-level traversal using a queue to accumulate and average node values, helping you understand and implement efficient tree traversal solutions in coding interviews.

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] ...
