Hi, asked a question earlier regarding the following problem! So sorry, I was able to understand the explanation of the expert, however the code was in C++ which I am still unfamiliar with. Wanted to ask how we can go about solving this problem in java? Question: You have probably heard about the deque (double-ended queue) data structure, which allows for efficient pushing and popping of elements from both the front and back of the queue. Depending on the implementation, it also allows for efficient random access to any index element of the queue as well. Now, we want you to bring this data structure up to the next level, the teque (triple-ended queue)! The teque supports the following four operations: push_back x: insert the element ?x into the back of the teque. push_front x: insert the element ?x into the front of the teque. push_middle x: insert the element ?x into the middle of the teque. The inserted element ?x now becomes the new middle element of the teque. If ?k is the…

You can use inheritance or composition to design the data structures for stacks and queues. Discuss the pros and cons of these two approaches.

Please use Python for this question: Question 1. Inheritance: You MUST use inheritance for this problem. A stack is a sequence container type that, like a queue, supports very restrictive access methods: all insertions and removals are from one end of the stack, typically referred to as the top of the stack. A stack is often referred to as a last-in first-out (LIFO) container because the last item inserted is the first removed. Implement a Stack class using inheritance. inherit the following methods below: a. Constructor/_init__ - Can construct either an empty stack, or initialized with a list of items, the first item is at the bottom, the last is at the top. b. push() - take an item as input and push it on the top of the stack c. pop() - remove and return the item at the top of the stack d. isEmpty() - returns True if the stack is empty, False otherwise e. [] - return the item at a given location, [0] is at the bottom of the stack f. len() - return length of…
