Analyze the following series of insertion (I) and deletion (D) operations is provided for debugging a module, coded in C language, being applied on STACK and circular Queue. The given series is: I D I I I D D I I I I D I D I D D D I I Compute the position of TOP or any warnings message in case of STACK (Size = 5) Compute the positions of FRONT and REAR or any warning message in case of Circular Queue after each operation (Size = 5)
Please answer #2 for me. Write CLEARLY please. 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? Lay out your assumptions and solution process in your answer.
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.
The language a^n b^n c^n is not a CFL. Give a pushdown automaton with 2 stacks that accepts the language. (This shows that 2 stack PDAs are more powerful than a single stack PDA.)Your answer in table format must include the headings - state,stack 1,stack 2, new state, stack1 op, stack 2 op
Let #0(x) and #1(x) again denote the numbers of 0’s and 1’s in abinary string x, respectively. Design a PDA to accept the following language. You may use either the “accept by final state” or the “accept by empty stack” mode.L = {x | x ∈ {0, 1}∗, #1(x) > #0(x)}
Given the following sequence of characters: DA&T!A ST*R&U!CT!&UR*ES. Consider the stack data structure, supporting two operations push and pop. Suppose that for the above sequence, each letter (such as DATA STRUCTURES) corresponds to a push of that letter onto the stack, each exclamation mark(!) corresponds one pop operation on the stack, each ampersand (&) corresponds one peep operation on the stack and each asterisk (*) corresponds two pop operations on the stack. Show the sequence of values returned by the pop operations. Also, display the remaining elements in the stack after all the push and pop operations.
(a) Design a PDA P that recognizes the language L = {x#y : x, y ∈{1}∗∧ |x| > |y|} over the alphabet Σ = {1, #}. Draw a state diagram according to the format of the textbook and the slides,i.e., start with an empty stack. Furthermore, ensure that every move either pushes or pops, but not both.(b) Obviously, you can easily create a CFG for such a trivial language like L. Here, you are asked to not just produce any CFG for L, but follow the procedure PDA-to-CFG to obtain such a grammar. Even for such a simple PDA, the grammar would be a bit lengthy. Therefore, we make one modification. You don’t have to write any rules that involve variables that generate the empty language. Such rules would have no effect anyway.
Implement a complete class in c ++ code that represents a stack. The stack must contain the operations push and pop with ordinary semantics. Both operations must be 0 (1).
Execute a program to implement a linked stack to check for the balancing ofthe following pairs of symbols in a Pascal program. The name of the source Pascalprogram is the sole input to the program.Symbols: begin end, ( ), [ ], { }.(i) Output errors encountered during mismatch of symbols.(ii) Modify the program to set right the errors.
Pseudocodes can be written using the operations PUSH(S,X), POP(S,X), PRINT(X), EMPTY STACK(S), and TOP OF STACK(S), which returns the top element of stack S. i) assign X to the bottom element of stack S, leaving the stack empty;ii) assign X to the bottom element of the stack, leaving the stack unchanged;iii) assign X to the nth element in the stack (from the top), leaving the stack unchanged.
What would be the contents of the initially empty queue Q1 and stack S1 (show the results from left to right where the left side represents the bottom in case of the stack and the rear in case of the queue) after the following code is executed : S1=Stack.Stack() Q1=Queue.Queue() aList=[59, 8, 30, 4, 9, 15, 16, 2, 31, 14, 18] for i in aList: if i==16 or i==9: S1.pop() Q1.dequeue() Q1.enqueue(i) elif i>14: S1.push(i) else: Q1.enqueue(i)
Solve the following problems using Scala with Classic Akka Actors. For each problem, also implement client actors for sending the messages required for beginning the required computation. Use these client actors for testing your application actors. Recall the card shuffling problem. In a Faro shuffle, a stack of cards is broken up into two, and then combined so that a card from one sub-stack is followed by one from the other, and so on. A perfect Faro shuffle breaks up the stack into two sub-stacks of exactly the same size, and then combines them in the manner described above. An out-shuffle results in the top and the bottom cards of the stack remaining the same after the shuffle; an in-shuffle results in these cards becoming the second and the second last cards of the shuffled stack. Implement a shuffler actor which accepts a message containing a deck of cards as a list of even length, an integer indicating the number of times that the deck is to be shuffled, and a boolean…
