You are tasked with implementing a function that performs an in-order traversal of a binary tree. In a binary tree, each node has a value and potentially two child nodes (left and right). The in-order traversal visits the left subtree first, then the current node, and finally the right subtree. You are required to return the values of the nodes in the order they were visited as a list. Here’s the function signature you need to implement: “`python def inorder_traversal(root: TreeNode) -> List[int]: “` Where `root` is the root node of the binary tree, and `TreeNode` is defined as follows: “`python class TreeNode: def __init__(self, value=0, left=None, right=None): self.value = value self.left = left self.right = right “` Consider edge cases where the tree might be empty (i.e., `root` is `None`). Your function should be efficient and handle various tree structures effectively.

Imagine you’re diving into the world of binary trees, and you’ve been given the task of implementing a function for in-order traversal. If you’re not familiar with binary trees, it’s a structure where each node has a value and can ...Read more
