Assume you perform a breadth-first search on a stack rather than a queue. Is it still calculating the quickest paths?
10.7 Suppose you wish to reverse the order of elements of a queue. Usingonly Queue operations, describe how this would be done. (Hint: While you can’tuse a stack, you can use something similar.)10.8 Over time, the elements 1, 2, and 3 are pushed onto the stack, amongothers, in that order. What sequence(s) of popping the elements 1, 2 and 3 offthe stack are not possible?
Consider that you have a stack S and a queue Q. Draw S and Q after executing the following operations (Op). You have to indicate for each operation, the stack or the queue content in addition to the index value of the top (stack) or the front and the rear (queue) Stack S; Queue Q; int a=3, b=7
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. -
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: 1,10,2,20,3,30,4,5
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?
Please answer the following, #3. Write clearly please. If postfix math is easy to analyze with a stack, would prefix math like ”/ * + 2 2 8 4” (which equals 8) be easy to analyze with a queue?
