Answer #1

Advantages of using singly linked list -

1. List maintains the pointer to keep track of each element and it is easy to track while building a stack.

2.Operation performed (Insertion, Deletion) are in complexity of O(1).

Advantages of using an Array -

1.Push, Pop in the stack can be performed in O(1) if we use an array to build a stack.

2.Memory Overhead of an array is better than that of linked list.

    You implemented a stack as a singly linked list (you add at the head and remove from the head). Perform the following operations on the stack: push(50), push(90), push(30), push(53), push(52), pop(), push(51), pop(), pop(), push(100), and push(15). After all the operations are performed, draw the resulting linked list. Indicate which node is the top of the stack in the resulting linked list.

    1.If a list is implemented as a singly linked stack, give the big-O worst-case time complexity of the following operations (as usual use the smallest standard big-O category that works: a) push_front, b) push_back, c) lookup, d) read the i'th member 2.Repeat question 3 for a dynamic array (for example, as in the C++ vector class)

    1)Given a Stack implemented with a Linked List, and an O(1) implementation of push and pop,show the Linked List after the following commands are executed: Stack myStack = new Stack(); myStack.push(20); myStack.push(40); myStack.pop(); myStack.push(60); myStack.push(80); 2)If the same commands were used but the Stack was implemented with an Array with maximum size of 10, show what the array would look like after all these commands are executed. Assume O(1) implementation of push and pop here as well. 3)Given a Queue...

    Insert elements into a hash table implemented using chain hashing, as an array of linked list in which each entry slot is as a linked list of key/value pairings that have the same hash (outcome value computed using certain hash function). You are allowed to use “Hash Function”, h(k) = k % x where, x is the value you will need to decide to use, that you find appropriate for this implementation. The main requirements are the following: 1. Input:...
