DELE Algorithm Questions: What to Expect on the Exam

The DELE section of the Algorithms practice test covers deletion operations across common data structures, including singly linked lists, doubly linked lists, binary search trees, and hash tables. Expect questions on time complexity, where DELE operations range from O(1) for hash tables to O(log n) for balanced BSTs and O(n) for unsorted arrays. Pay close attention to edge cases like deleting the root node, handling duplicate keys, and rebalancing AVL or red-black trees after a DELE operation.
