PruneRoot is a term encountered in computer science and related disciplines to describe an operation that modifies a rooted tree or hierarchical structure by altering the root or removing top-level components. There is no single universal standard, so the exact semantics of pruneRoot vary with context and implementation.
Common variants include deleting the root node and promoting one of its children as the new root,
In machine learning and decision-tree contexts, pruneRoot can refer to pruning policies that collapse the top-level
Implementation considerations depend on the chosen representation. In pointer-based trees, updating parent pointers, child lists, subtree
