"WebMar 24, 2024 · However, the algorithms differ a bit from each other, depending on the type of the graph. Let’s shortly remember the problem definition. The LCA between two nodes and in a graph is the deepest node , such that it is an ancestor of both and . In case DAG is a special case of a graph, the might be 0, 1, or more LCAs between any two nodes. " - Algo graph
