WebLCA of two nodes A and B is the lowest or deepest node which has both A and B as its descendants. Note: It is defined that each node is a descendant to itself, so, if there are two nodes X and Y and X has a direct connection from Y, then Y is the lowest common ancestor. If out of 2 nodes only one node is present, return that node. Web3 mrt. 2024 · Problem Note.
