In-order traversal is a method of visiting all the nodes in a binary tree in a specific sequence: first the left subtree, then the node itself, and finally the right subtree. This technique allows for the nodes to be processed in a non-decreasing order when dealing with binary search trees, making it a fundamental operation for various applications, including sorting and searching algorithms.
congrats on reading the definition of In-Order Traversal. now let's actually learn it.
