What is a stack and how is it different from a queue?

• A stack is the same as a queue because they both follow the LIFO principle.

• A stack is different from a queue because it follows the FIFO principle, while a queue follows the LIFO principle.

• A stack is different from a queue because it follows the LIFO principle, while a queue follows the FIFO principle.

• A stack is similar to a queue because they both have a fixed size.

Explain the concept of LIFO and FIFO in the context of stacks and queues.

• FIFO means the last element added will be the first one to be removed in queues

• LIFO means the first element added will be the first one to be removed in queues

• In the context of stacks, LIFO means that the last element added will be the first one to be removed, while in the context of queues, FIFO means that the first element added will be the first one to be removed.

• LIFO means the first element added will be the first one to be removed in stacks

What are the basic operations that can be performed on a stack?

• insert, delete, access

• push, pop, empty

• add, remove, view

• put, take, observe

How are stacks and queues implemented using arrays?

• Queues can be implemented using arrays by using the push and pop operations.

• Stacks can be implemented using arrays by using the enqueue and dequeue operations.

• Stacks can be implemented using arrays by using the push and pop operations. Queues can be implemented using arrays by using the push and shift operations.

• Stacks can be implemented using arrays by using the add and remove operations.

What are the basic operations that can be performed on a queue?

• add and remove

• enqueue and dequeue

• insert and extract

• push and pop

Explain the concept of a linked list and its advantages over arrays.

• Linked lists require contiguous memory for storage

• Linked lists allow for efficient insertion and deletion of elements, as they do not require shifting of elements to maintain contiguous memory.

• Linked lists are less memory efficient than arrays

• Arrays allow for efficient insertion and deletion of elements

Explain the concept of a linked list with an example.

• Example: 1 -> 2 -> 3 -> 4 -> null

• Example: 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7

• Example: 1 -> 2 -> 3 -> 4 -> 5 -> 6

• Example: 1 -> 2 -> 3 -> 4 -> 5

What is an abstract data type (ADT) and why is it important in programming?

• An abstract data type (ADT) is a specific data type that can only store integers, and it is important in programming because it allows for faster execution of code.

• An abstract data type (ADT) is a type of data that is only used in advanced programming languages, and it is important because it simplifies the syntax of the code.

• An abstract data type (ADT) is a theoretical concept that defines a data type based on its behavior and operations, rather than its implementation.

• An abstract data type (ADT) is a type of data that is only used in hardware programming, and it is important because it reduces the memory usage of the program.

Explain the process of implementing a stack using an array.

• The process of implementing a stack using an array involves using the push and shift operations to add and remove elements from the end of the array, respectively.

• The process of implementing a stack using an array involves using the push and pop operations to add and remove elements from the end of the array, respectively.

• The process of implementing a stack using an array involves using the insert and delete operations to add and remove elements from the middle of the array, respectively.

• The process of implementing a stack using an array involves using the add and remove operations to add and remove elements from the beginning of the array, respectively.

What are the advantages and disadvantages of using arrays to implement a stack?

• The advantages of using arrays to implement a stack include easy access to the top element and simple resizing. The main disadvantage is the potential costly operation of resizing the array when it becomes full.

• The advantages of using arrays to implement a stack include limited storage capacity and slow retrieval of elements.

• The disadvantages of using arrays to implement a stack include easy access to the top element and simple resizing.

• The advantages of using arrays to implement a stack include complex access to the top element and difficult resizing.
