  2. Outline • Lab 6 Recap / Sorting • BST Node Removal

  3. O(n2) Sorting Algorithms • Bubble sort • Bubble the largest element to the end in each pass • Insertion sort • Insert the next element into the sorted portion of the list • Selection sort • Find the smallest item and put it in its proper location

  4. O(nlog(n)) Sort Algorithms • Merge Sort • Break the problem up until you have 1 or 2 items and put them in order • Merge the sorted lists O(k) where k is the size of the small lists • T(n) = 2T(n/2) + O(n) === O(n*log(n)) (masters theorem)

  5. BST Remove • If the node has no children simply remove it • If the node has a single child, update its parent pointer to point to its child and remove the node

  6. Removing a node with two children • Replace the value of the node with the largest value in its left-subtree (right-most descendant on the left hand side) • Then repeat the remove procedure to remove the node whose value was used in the replacement

  7. Removing a node with two children
