Recursive Algorithms

Recursive Algorithms. In this technique, we define a procedure that is allowed to make calls to itself as a subroutine Those calls are meant to solve sub-problems of smaller size Recursive procedure should always define a base case that can be solved directly without using recursion.

Heap Sort

Heap Sort. CS 105. Using a heap to sort. Using a heap-based priority queue, sorting can be done in O( n log n ) time Insert all n elements in the priority queue Repeatedly remove the elements from the priority queue (they will come out sorted)

Chapter 05

Chapter 05. Trees (Part II). 5.2.3 Representations. Array Representation. We can use an array to represent a complete binary tree. Lemma 5.4 If a complete binary tree with n nodes in given, then for any node with index i, 1?i?n, Parent(i) is at if i > 1. If i=1, node i is the root.
