An Abstract Queue (Queue ADT) is an abstract data type that emphasizes specific operations: Uses a explicit linear ordering, insertions and removals are performed individually, there are no restrictions on objects inserted into (pushed onto) the queue - that object is designated the back of the queue,. This topic discusses the concept of a queue: Description of an Abstract Queue, list applications, implementation, queuing theory, standard template library. | Review Introduction Stack in our life Stack Operations Stack Implementation Stack Using Array Stack Using Linked List Use of Stack Polish Notation Prefix Infix Postfix Precedence of Operators Converting Infix to Postfix Evaluating Postfix Prefix, Infix, Postfix Two other ways of writing the expression are + A B prefix (Polish Notation) A B + postfix (Reverse Polish Notation) The prefixes “pre” and “post” refer to the position of the operator with respect to the two operands. A primary concern for this course is efficiency. You might believe that faster computers make it unnecessary to be concerned with efficiency. However So we need special training. Prefix, Infix, Postfix Consider the infix expression A + B * C We “know” that multiplication is done before addition. The expression is interpreted as A + ( B * C ) Multiplication has precedence over addition. A primary concern for this course is efficiency.
