inorderleft
Inorderleft is a term used in some programming contexts to denote a specific form of in-order traversal of a binary tree. In many codebases, it identifies an in-order traversal that processes left subtrees before the node and then the right subtree. Because in-order traversal by definition visits left before the root, "inorderleft" is often synonymous with the standard in-order traversal and is not standardized as a distinct algorithm in formal literature. The name is primarily found in source code, tutorials, or library APIs to differentiate from other traversal variants such as pre-order or post-order, or from left-imposed variants like inorderright used for emphasis.
A typical inorderleft traversal visits the left child, then the current node, then the right child. This
