Advanced Data Structures and Algorithms 254 This chapter covers the material in Topic 5 of the HL IB Computer Science Syllabus. The chapter follows the syllabus in the exact order it is speciﬁed and begins with a discussion of terminology. Infix, Prefix and Postfix Expressions This type of notation is referred to as infix since the operator is in between the two operands that it is working on. Consider another infix example, A + B * C. The operators + and * still appear between the operands, but there is a problem. Which operands do they work on? Does the + work on A and B or does the * take B and C? The expression seems

John Edgar 12 A stack only allows items to be inserted and removed at one end We call this end the top of the stack The other end is called the bottom Access to other items in the stack is not allowed John Edgar 13 A stack is a natural choice to store data for postfix notation Operands are stored at Data in these structures can be modified, added or deleted at any stage. (b) A stack is a Last In First Out data structure; that is, the last item placed in the stack is the first one to be removed.

Polish Notation is a way of expressing arithmetic expressions that avoids the use of brackets to define priorities for evaluation of operators. Polish Notation was devised by the Polish philosopher and mathematician Jan Łukasiewicz (1878-1956) for use in symbolic logic. In his notation, the operators preceded their arguments, so that the Algebraic Expression •Operator Precedence • Parenthesis ( ) • Exponentiation ^ (not a C++ expression) • Multiplication and Division * / • Addition and

Data in these structures can be modified, added or deleted at any stage. (b) A stack is a Last In First Out data structure; that is, the last item placed in the stack is the first one to be removed. Reverse Polish Notation was a good tool in my education for understanding parse trees and tree data structures in general. It's also useful if anyone has any interest at all in programming in any of the Lisp family of languages (Clojure, emacs-lisp, scheme etc..).

A structure chart looks very similar to a hierarchy chart. The main difference is that we include interfaces to indicate the movement of data and control information. The main difference is that we include interfaces to indicate the movement of data and control information. Remember that in the generic programming paradigm, every data structure is supposed to provide encapsulation of the data collection, enabling the programmer to interact with the entire data structure in a meaningful way as a container of data .

Prefix notation can also be nicely evaluated by a program using a stack as data structure. Infix notation is easy for people to evaluate; prefix and postfix are easy for programs to evaluate. Data Structures UNIT III Model Question Answer Q.1. Define Stack? What are the different primitive operations on Stack? Ans: Stack: A stack is a linear structure in which items may be added or removed only at one end. Stacks are data structures that allow insertions and deletions operations only at the beginning or the end of the list, not in the middle. A stack is a last in, first out (LIFO
