Structured English

Structured English uses a simple English language to make structured programming easier for non-professionals. The program is divided into various parts that are known as logical statements. These statements are written in a simple English language.

A ring buffer, or circular queue, is a FIFO data structure of a fixed size N. It is useful for transferring data between asynchronous processes or for storing log files. When the buffer is empty, the consumer waits until data is deposited; when the buffer is full, the producer waits to deposit data. Develop an API for a RingBuffer and an implementation that uses an array representation (with circular wrap-around)

∑ = {C,A,G,T}, L = { w : w = CAjGnTmC, m = j + n }. For example, CAGTTC ∈ L; CTAGTC ∉ L because the symbols are not in the order specified by the characteristic function; CAGTT ∉ L because it does not end with C; and CAGGTTC ∉ L because the number of T's do not equal the number of A's plus the number of G's. Prove that L ∉ RLs using the RL pumping theorem.
Question 42 What makes implementing a queue with a Doubly Linked List relatively easier than implementing a queue with a typical array, where all elements stay in adjacent locations? There's no need to explicitly shift the elements of a Linked List to the front, as there would be in an array. There's no need to keep track of how many elements are present, as there would be in an array. There is no advantage to using a Linked List implementation over an array implementation. There's no need to keep track of a front and a back, as there would be in an array.
