PPT-Stacks & Recursion Stack

push pop LIFO list only top element is visible t op Defining the ADT Stack Data a linear collection of data items in which all operations occur at one end called the top Basic Operations. CS16: Introduction to Data Structures & Algorithms. 1. Tuesday, February 9, 2016. Abstract Data Types. An abstract data type (ADT) is an abstraction of a data structure. An ADT specifies the type of data stored and the different operations you can perform on it. Hongfei. Yan. Mar. 16, 2016.

A recursive method is capable of solving only the base case(s) . Each method call divides the problem into two conceptual pieces: a piece that the method knows how to do and a Recursion II Fundamentals of Computer Science Outline Recursion A method calling itself A new way of thinking about a problem A powerful programming paradigm Examples: Last time: Factorial, binary search, H-tree, Fibonacci Recursion Refresher.

Recursion – Recursive Calls to a Function. To review a topic you should have covered, recursion in programming is the act of a function or procedure calling itself or otherwise making use of itself in its definition..
