The video tutorial explains the delete method for binary search trees, focusing on maintaining tree order during deletion. It covers three scenarios: deleting leaf nodes, nodes with one child, and nodes with two children. For leaf nodes, the process is straightforward as they have no children. Nodes with one child require re-linking the parent to the child. The most complex case involves nodes with two children, where the node is replaced by the minimum value from the right subtree or the maximum from the left. The tutorial concludes with interview tips.
