Implement different search algorithms : BST - Deleting nodes with 2 children

The video tutorial covers the development of a delete method for a binary tree, focusing on handling various scenarios such as deleting a root node, nodes with one child, and nodes with two children. The instructor identifies and resolves errors, emphasizing the importance of formalizing test cases. The tutorial includes implementing a helper method to find the minimum value in a right subtree and testing the method to ensure all cases are handled correctly. The video concludes with a reflection on the complexity of the task and the incremental approach taken.
