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.
Create a process to leave the other items of a linked stack unaltered while removing the nth member (from the top).
A 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. -
The contents of the linked stack L_S and linked queue L_Q are swapped in both operations. While WHAT_IS_COOKING1 exchanges the data items of the lists, WHAT_IS_COOKING2 just manipulates the pointers and so appears more elegant.
What is the time complexity of pushing and popping items to/from a stack containing n items, respectively? What is the time complexity of dequeue and enqueue operations on a FIFO queue containing n itmes, respectively?Suppose you push 1, 4, 7, and 10 onto the stack. Then you pop two times. Then add 3 to the number at the top and push the sum to the stack. Which are the numbers left on the stack? (write from bottom to the top). As other items are inserted and removed, does a particular item in a queue move along the array from lower to higher indices, or higher to lower, or not move?
Implement a stack S with two queues Q1 and Q2 so that the operations PUSH (S, X) and POP(S, Y), where S is presumably a stack and X is the element to be added to S and Y is the element removed from S, are handled by the queues that function as a stack as a whole. Assume that only queues are accessible to ADT's ENQUEUE, DEQUEUE, and EMPTYQUEUE operations.Show how your function operates on a list of items (a, b, and c) that will be used as a stack by the queues Q1 and Q2.
Implement a queue Q with two stacks S1 and S2, so that the stacks that operate together as a queue may perform the operations ENQUEUE(Q, X) and DEQUEUE(Q, Y), where Q appears to be a queue and X is the element to be inserted into Q and Y is the element to be removed from Q. Assume that the ADT operations PUSH, POP, and EMPTYSTACK are only available for stacks.Show how your technique works on a list a, b, c, which will be utilised as a queue by the stacks S1 and S2.

Implement a method transfer in class LinkedStack. This method should transfer all elements of a stack sourceS to another stack targetS so that the element that starts at the top of sourceS is the first one to be inserted in targetS, and the element at the bottom of sourceS ends up at the top of targetS. The operation should result in sourceS being an empty stack. Test this method in the main method of LinkedStack.
There is a data structure called a drop-out stack that behaveslike a stack in every respect except that if the stack size is n,then when the n+1 element is pushed, the first element is lost.Implement a drop-out stack using links
The PostfixEvaluator class uses the java.util.Stack class to create thestack attribute. The java.util.Stack class is one of two stack implementationsprovided by the Java Collections API. We revisit the other implementation, theDeque interface, in Chapter 13.The evaluate method performs the evaluation algorithm described earlier, supported by the isOperator and evalSingleOp methods. Note that in the evaluatemethod, only operands are pushed onto the stack. Operators are used as they areencountered and are never put on the stack. This is consistent with the evaluation algorithm we discussed. An operand is put on the stack as an Integer object, insteadof as an int primitive value, because the stack collection is designed to store objects.When an operator is encountered, the two most recent operands are poppedoff the stack. As mentioned above, the first operand popped is actually the secondoperand in the expression and that the second operand popped is the first operandin the expression.…
Can you explain in detail, line by line, what the attached algorithm is doing? I need further understanding. For further clarification the prompt asks the following: Write an algorithm Replace that takes a stack and two items. If the first item is in the stack, replace it with the second item, leaving the rest of the stack unchanged.
