Revone 60e08d3ac5 Successfully implemented recursive type inference for the BinaryTreeNode type by passing the node constructor through the constructor, effectively addressing the type inconsistency caused by invoking parent class methods after inheritance. 2023-08-22 22:50:16 +08:00
Revone d3f5dd4a9e edge1.data has type problem. After the uniform design, the generics of containers (DirectedGraph, BST) are based on the type of value.
