This PR optimizes the nodePrinted map in the printNode function by replacing it with a sync.Map. The original implementation used a standard map, which is not safe for concurrent access.
By using sync.Map, the code can safely handle concurrent access to the nodePrinted data structure, leading to better performance when running tests that involve concurrency.
