Enqueue isEmpty size first A can be used to preserve the order of a set of data. Queue Stack Software Heaps To add an element to a queue you use the method. push enqueue dequeue pop The shifting of elements in a noncircular array implementation creates an complexity.

Front Rear Middle None of the above A circular array implementation of a queue is more efficient than a fixed array implementation of a queue because elements never have to be added removed shifted initialized Answer the following questions. Postfix Expressions Convert the following infix expression to an equivalent postfix expression: (4 * 5 - (3 + 6)) * 5/2 Apply the postfix evaluation rule to the postfix expression you obtained from Part a) using a stack to find the final answer of the expression. You should show the contents of the stack before any operator is encountered.
