- Consider the following stack, which can be written as [70, 10, 50, 80, 20] i.e. the "top" of the stack is the first element in the list Consider the following code (written as pseudocode): myfunction( stack1 ) stack2 = createStack() while stack1 is NOT empty value = top(stack1) pop(stack1) while stack2 is NOT empty and top(stack2) > value push(stack1, top(stack2)) pop(stack2) push(stack2, value) print(stack2) // Prints the current stack as [element_1, element_2, ..., element_n] return stack2 From the answers below, select the correct output for the first 4 print statements if myFunction is executed with: myFunction( [ 70, 10, 50, 80, 20] )Sort the stack values either ascending or descending without using stack builtin classes for example Stack before sorting : 5 | -2 | 9 | -7 | 3 where 3 is the top elementStack after sorting : -7 | -2 | 3 | 5 | 9 where 9 is the top element by using c/c++ labguageRefer to the code fragment below and convert the following Queue structure into a Stack structure. You should create a reference called S1 for the stack structure. Code: Queue Q1 = new LinkedList (); Q1.add(“Sandra”); Q1.add (15); Q1.add (200); Q1.add (‘# ‘); Q1. remove (); System.out.println(Q1); System.out.println(Q1.peek()); Q1.add(“Mary”); System.out.println(Q1);

Given a stack, a function is_consecutive takes a stack as a parameter and thatreturns whether or not the stack contains a sequence of consecutive integersstarting from the bottom of the stack (returning true if it does, returningfalse if it does not). For example:bottom [3, 4, 5, 6, 7] topThen the call of is_consecutive(s) should return true.bottom [3, 4, 6, 7] topThen the call of is_consecutive(s) should return false.bottom [3, 2, 1] topThe function should return false due to reverse order. Note: There are 2 solutions:first_is_consecutive: it uses a single stack as auxiliary storagesecond_is_consecutive: it uses a single queue as auxiliary storage"""import collections def first_is_consecutive(stack): storage_stack = [] for i in range(len(stack)): first_value = stack.pop() if len(stack) == 0: # Case odd number of values in stack return True second_value = stack.pop() if first_value -…Stack, Queue and Deque5.1. Understand the basic operations for Stack, Queue and DequeExample: Suppose that Queue q is implemented by a circular array data with the size 3. Please drawthe state of the Queue q and circular array data after each of the following steps.1) Queue q = new Queue();2) q.enqueue(5);3) q.enqueue (2);4) q.enqueue (9);
- Sort the stack values either ascending or descending without using stack builtin classes for eg Stack before sorting : 5 | -2 | 9 | -7 | 3 where 3 is the top elementStack after sorting : -7 | -2 | 3 | 5 | 9 where 9 is the top elementQuestion 1 Language: Java Refer to the operations below:Add (10 + 5)Add (4+8)Add (7*2)Add (90 – 3)Print listPrint peekRemove an item from the listPrint list1.1 Implement the operations above into a Queue structure called q1.1.2 Implement the operations above into a Stack structure called s1.Code in C One of the applications of a stack is to backtrack - that is, to retrace its steps. As an example, imagine we want to read a list of items, and each time we read a negative number we must backtrack and print the five numbers that come before the negative number and then discard the negative number. Use a stack to solve this problem. Use a stack and push them into the stack (without printing them) until a negative number is read. At this time, stop reading and pop five items from the stack and print them. If there are fewer than five items in the stack, print an error message and stop the program. After printing the five items, resume reading data and placing them in the stack. When the end of the file is detected, print the message and the items remaining in the stack. Sample Output 1 2 3 4 5 6 7 -1 7 6 5 4 3 9 6 4 3 -2 3 4 6 9 2 -3 Number of items left is less than five! Program is terminating! Project name : Backtrack Filenames: backtrack.h, backtrack.c,…
