Convert given flowchart into pseudocode.

Write the pseudo code for the attached flowchart that adds a series of user-entered numbers and terminates after displaying the sum when the user enters 0.

Array of Spices in Java

If I were to describe an every day situation, like being a chef at a restaurant, how would I implement an array (for inventory) of my spices (I would have a total of 20 spice bottles)? And, how would items in the array might be searched for or sorted? I don't need a full program, I just need pseudocode - a small example of ju ...continues

Describe how the use of primitives helps remove ambiguities in an algorithm’s representation.

Please modify this program so the application can handle multiple items.

Please modify this program so the application can handle multiple items. Use an array to store the items. The output should display the information one product at a time, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. ...continues

Automata and Computability (A13)

Say that string x is a prefix of string y if a string z exists where xz = y and that x is a proper prefix of y if in addition x  y. In each of the following parts we define an operation on a language A. Show that the class of regular languages is closed under that operation. a. NOPREFIX (A) = {w  A| no prope ...continues

Automata and Computability

Let G be CFG in Chomsky normal form that contains b variables. Show that, if G generates some string using a derivation with more than b steps, L (G) is infinite.

Automata and Computability (A18)

Consider the language B = L (G), where G is the grammar given in Exercise 2.13 (page 121). The pumping lemma for context-free languages, Theorem 2.19 (page 115), states the existence of a pumping length p for B. What is the minimum value of p that works in the pumping lemma? Justify your answer.

Automata and Computability

A Turing machine with doubly infinite tape is similar to an ordinary Turing machine except that its tape is infinite to the left as well as to the right. The tape is initially filled with blanks except for the portion that contains the input. Computation is defined as usual except that the head never encounters an end to the t ...continues
