Isomorphic problem in computer science typically refers to a situation where two data structures or graphs have the same structure and properties, even though they may be represented differently. In the context of浙江大学的编程题目， isomorphic problems could involve tasks where you need to determine if two trees (like binary trees or directed graphs) are structurally equivalent despite different node labels or numbering. For example, a common task might be to check whether two given trees have the same shape but different contents, meaning their nodes and connections match regardless of the specific values stored at each node. This can be solved by comparing the adjacency lists or recursively checking if the left subtree of one tree is isomorphic to the right subtree of another tree, and vice versa. Here's a simple pseudocode for checking if two trees are isomorphic: ```python def isIsomorphic(tree1, tree2): def get_node_hash(node): return tuple(sorted(node.val)) + get_node_hash(node.left) + get_node_hash(node.right) return get_node_hash(tree1.root) == get_node_hash(tree2.root) ```
