Racket: Execute these lists: ( (lambda (x) (* x x)) 1) ( (lambda (x) (* x x)) 2) ( (lambda (x) (+ x x)) 3) ( (lambda (x) (- x x)) 4) ( (lambda (x) (/ x x)) 5) ( (lambda (x) (modulo x x)) 6) ( (lambda (x) (modulo (+ x 2) x)) 6) Explain clearly what these expressions seem to mean
Summarize the structures of a stack and a queue. Give a C++ fragment of code that shows how either a queue or a stack is created and how its elements are accessed. This assignment deals with stacks and queues using C++ language. PLEASE create an original code that works and please guide me on how to create a code. I am a novice and I would love how to create my own code!
Two approaches used to write the specifications for operations between a sender and a receiver object (e.g., Stack) are based on design by contract and defensive design. Using an IDE (e.g., Eclipse) write well-documented code for the Stack class using both approaches (StackDC, StackDD). Assume the Stack stores Integer objects with a maximum size of 5 objects. The Stack must be implemented using a LinkedList from the Java library.
One linear structure might be more applicable than another. (A) Can a Stack be used to implement a Queue? How complex are the Queue operations individually? (b) Can a Stack be implemented using a Queue? What level of complexity do the different Stack techniques have?

In a programming language (Pascal), the declaration of a node in a singly linked list is shown in Figure P6.7(a). The list referred to for the problem is shown in Figure P6.7(b). Given P to be a pointer to a node, the instructions DATA(P) and LINK(P) referring to the DATA and LINK fields, respectively, of node P are equivalently represented by P↑. DATA and P↑.

What do the following commands do to the logical representation of the list T? i) ii) TYPE POINTER=NODE; NODE RECORD DATA: integer; LINK: POINTER END; VAR P, Q R: T POINTER (a) Declaration of a node in a singly linked list T 31 TE 57 12 (b) A singly linked list T iii) R₁.LINK: = Q iv) R₁.DATA: = P₁.DATA: Q₁.DATA + R₁.DATA Q: = P |R Figure P6.7.

Consider a standard stack data structure with a push and popoperation. What would be the exact complexity (not Big O) to print alln items in some stack and return it to its original order when finished?
Example 2.4; Build a multi-stack Push Down Automata (PDA) (it means you can use more than one stack, for example 3 stacks) to accept the language {a"b"a"b" | n21} over the alphabet E={a,b}. Please explain your design shortly and draw the PDA.
Construct a PDA for {a'b'|i # j}. State whether it is “accept by empty stack" or "accept by final state." Please also give a high-level description of your PDA. 7.
A singly linked list can be reversed by altering the nodes' pointers. The original list's nodes should still contain the data that the list represents.For instance, if a single linked list START is supplied, as in Figure P6.9(a), the list must be reversed using just the links, as in Figure P6.9(b).
∑ = {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.
