Python 3: Project-based Python, Algorithms, Data Structures - Hash project 2: Set up insert and hashing functionality fo

The video tutorial covers two linear data structures: stacks and queues. It explains their operations, such as push, pop, peek, and isEmpty for stacks, and enqueue and dequeue for queues. The tutorial also discusses the LIFO (Last In, First Out) principle for stacks and the FIFO (First In, First Out) principle for queues. Code implementations for both structures using linked lists are provided, highlighting the importance of tracking the head and tail nodes. The video concludes with practical examples and encourages viewers to experiment with the provided class files.

What is a key characteristic of linear data structures like stacks and queues?

• They are non-linear and cannot be implemented using linked lists.

• They are circular in nature.

• They are hierarchical.

• They are linear and can be implemented using linked lists.

In a stack, what does the stack pointer refer to?

• The size of the stack.

• The top of the stack.

• The middle of the stack.

• The bottom of the stack.

Which operation in a stack allows you to add an item to the top?

• IsEmpty

• Peek

• Push

• Pop

What does LIFO stand for in the context of stacks?

• Last In, First Out

• First In, Last Out

• Last In, Last Out

• First In, First Out

In the stack implementation, what is the purpose of the 'isEmpty' method?

• To view the top element of the stack.

• To check if the stack is empty.

• To remove an element from the stack.

• To add an element to the stack.

What is a key difference between stacks and queues?

• Stacks are non-linear, queues are linear.

• Stacks use FIFO, queues use LIFO.

• Stacks use LIFO, queues use FIFO.

• Stacks and queues both use LIFO.

In a queue, what does FIFO stand for?

• Last In, Last Out

• Last In, First Out

• First In, Last Out

• First In, First Out

What is the role of the tail in a queue?

• To track the front of the queue.

• To track the end of the queue.

• To track the size of the queue.

• To track the middle of the queue.

In the queue implementation, what does the 'remove' operation do?

• Removes an element from the end.

• Removes an element from the front.

• Adds an element to the end.

• Adds an element to the front.

What real-life scenario is similar to the operation of a queue?

• A stack of plates.

• A pyramid of blocks.

• A line at a supermarket cashier.

• A tree with branches.
