 2024-01-16 11:26:43 +08:00
Revone 56f1fabfca refactor: Renaming SENTINEL to NIL and placing the NIL node in the BinaryTree allows for direct equality checks in isNIL and isRealNode, avoiding excessive operations to improve performance.

Revone 5c9f4fd483 fix: #74 . Refactor: Implement the Tarjan algorithm separately for DirectedGraph and UndirectedGraph. In the previous design, the tarjan method was placed in the AbstractGraph class. However, Tarjan algorithm is used to find connected components in directed graphs and to solve bridges, articulation points, determine the presence of cycles (though not all), and biconnected components in undirected graphs. The algorithm for finding all cycles in the graph can be shared between directed and undirected graphs using the getCycles method. 2024-01-07 22:25:25 +08:00
