- Suppose that a client performs an intermixed sequence of (stack) push and pop operations. The push operations push the integers 0 through 9 in order on to the stack; the pop operations print out the return value. Circle the following sequence(s) that could not occur. a. 4 3 2 1 0 9 8 7 6 5 b. 2 1 4 3 6 5 8 7 9 0 c. 0 4 6 5 3 8 1 7 2 9 d. 4 6 8 7 5 3 2 9 0 1Create a collection. Along with GETMAX, MAXSTACK offers the ADT commands PUSH, POP, and EMPTYSTACK and performs similar operations to a standard linked stack. The GETMAX function keeps track of the largest stack member. Can the collection be constructed using GETMAX, which only requires O(1) time complexity? don't copy old bartleby answer it's wrongSuppose we begin with an empty stack, and perform the following operations: push(0), push(4), push(7), push(8), pop(), pop(), peek(), push(3), push(5), peek(), push(10), pop(), peek(), pop(), pop(), push(7), push(6), pop(), pop(), pop(), push(10). What is contained on the stack when we are done? Write out the contents from top to bottom.
- It is known that the sequence of the output of a string of integers is from left to right, respectively: 35, 78, 42, 59, 11, 93, 27, 66, 85, and it is known that the current results of the Linked Stack are as shown in the attached figure, it is possible What is the correct sequence of Stack operations (push and pop)? (multiple choice questions)Write a JAVA program that will maintain a phone directory using a Linked-List. The program should be able to perform the following operations: Add persons details (first name, last name, phone number, city, address, sex and email) to the phone directory, where phone numbers in the directory have to be unique. (Note: each person record will store in one node in the linked-list and insert each person to the last) Delete any person details by a given phone number. Update telephone number by providing person first name. Display all details of persons from a phone directory. Search telephone number based on person first name. (Note: use sequential search to find all telephones for the given first name) Sort all persons in the phone directory ascending based on person first name. (Note: use bubble or selection sort to arrange the entire phone directory)Given the following stack: P W H K M S B G Assuming Top is at G, what is the results for the following sequence of commands: pop(), pop, push ("J"), push ("X"), push("E"), pop() Select one: A. P W H K M J X E B. P W H K M X E J C. P W H K M S J X D. P W H K M E X J
- Write a JAVA program that will maintain a phone directory using a Linked-List. The program should be able to perform the following operations: 1) Add persons details (first name, last name, phone number, city, address, sex and email) to the phone directory, where phone numbers in the directory have to be unique. (Note: each person record will store in one node in the linked-list and insert each person to the last) 2) Delete any person details by a given phone number. 3) Update telephone number by providing person first name. 4) Display all details of persons from a phone directory. 5) Search telephone number based on person first name. (Note: use sequential search to find all telephones for the given first name) 6) Sort all persons in the phone directory ascending based on person first name. (Note: use bubble or selection sort to arrange the entire phone directory) Project Outputs The output has to display a menu of choices. Then the user can select which operation want to perform.…Use java language please 1.Write a method “mergeQueueStack” that takes a queue as a parameter of type: Queue of integers and a stack as a second parameter of type: Deque of integers Remove all the items from the queue and remove all the items from the stack then add them to a LinkedList by alternating between an item from queue then an item from stack. Don’t assume initially both the queue and the stack have the same number of items. The method should return the linked list of type integers. Example: If queue has : 1,2,3,4,5 and stack has 10, 20, 30 (where 10 is at top of the stack) then the linkedList should contain: 1,10,2,20,3,30,4,5A SpecialStackTM is a stack modified to support the following two operations: PUSHCLEAR(v) successively pops consecutive items from the top of the stack that are less than u, then pushes v onto the stack. POP() deletes the item at the top of the stack. Assume these operations are implemented using a singly-linked list. PUSHCLEAR(v) iter- ates through the linked list to pop the applicable items and then adds v to the beginning. POP() deletes the first item. (a) Describe the ordering of values on the stack. (b) Explain how a single call to PUSHCLEAR(V) could take (n) time. (c) If we assume that every operation takes linear time, we get a naive bound of O(n²) on the total runtime. But this doesn't consider the fact that these expensive operations happen infrequently so let's analyze it more closely. Show that any sequence of n operations takes O(n) time. -
- There is one stacks and one queue q and then following operations are performed upon these two. Push A, enqueue B, push C, pop, pop, enqueue D, push E, dequeue, enqueue F .What is the total number of elements, which are left in the queue and stack in the end.A certain stack contains (bottom to top, from left to right): s = [1, 4, 1, 3, 5, 3, 1, 4, 5, 1, 2] Assume that printing pop operations print number popped (e.g. print(q.pop()) prints 2 in the terminal), how can we output the numbers 1, 4, 5, and 1 in that exact order exactly in 9 operations: There are only 2 options: s.pop() print(s.pop()) (Don’t make an entire code of it answer it like it was shown in the picture)Create a stack S of ten elements. Take a number x from the user and delete the elements smaller than or equal to X from the stack.Example: Suppose your initial stack is S where you pushed 10 elements as below- Top {9, 3, 4, 15, 20, 1, 6, 4, 9, 10} Bottom4. X is taken as input and X= 6. Then pop out and remove the elements smaller than or equal to X. Finally, the stack will look like-Top {9, 15, 20, 9, 10} BottomYou can use only one additional queue to solve this problem.In c++ please
