62e55b84bd [graph] The getAllPathsBetween method in the [graph] provides a 'limit' parameter to control this exponential time complexity method from entering into a deadlock state. The getMinPathsBetween method, by default, calls the Dijkstra method to avoid invoking the excessively high time complexity method, getAllPathsBetween. 2023-11-04 21:23:02 +08:00

3a86a5c37d [binary-tree, graph] Replace all code that uses Arrays as makeshift Queues with actual Queues to improve efficiency. [binary-tree] Remove most methods for calculating sums and modifying properties, adopting a generic callback-based design. [bst] Enable default batch addition in BST using sorted binary insertion to maintain tree balance as much as possible. 2023-10-21 23:56:14 +08:00

9764f2a5c6 [binary-tree, graph] In order to optimize the design of Binary Trees, unnecessary abstract classe removed, while enforcing method constraints between base classes and subclasses through interfaces. For Graph, it is necessary to use an abstract class as the base class, and interface constraints should be applied. Any data structures that are not within the scope of the plan deleted. 2023-10-17 21:06:41 +08:00
