The video tutorial explains the implementation of a delete method in a tree structure. It covers the initial setup, testing for non-existent values, and the process of deleting nodes, including those with children. The tutorial emphasizes understanding through a step-by-step approach, using if-else conditions and recursive calls. It avoids tracking parent nodes directly in the node class to adhere to node principles. The tutorial concludes with enhancements to the recursive function to handle various scenarios.
