Scala & Spark-Master Big Data with Scala and Spark - Push and Pop in Stack

The video tutorial explains the fundamental operations of a stack data structure, focusing on the push and pop functions. It provides a step-by-step guide on implementing these operations in an IDE, demonstrating how to add and remove elements from the stack. The tutorial emphasizes the importance of understanding stack operations and prepares viewers for more advanced topics in future videos.

What is the primary function of the push operation in a stack?

• To remove data from the bottom of the stack

• To find the maximum element in the stack

• To add data to the top of the stack

• To sort the stack elements

Which operation is used to remove the top element from a stack?

• Insert

• Delete

• Pop

• Push

After pushing the elements 1, 2, and 3 onto a stack, what will be the order of elements from top to bottom?

• 1, 2, 3

• 3, 2, 1

• 1, 3, 2

• 2, 3, 1

What happens to the stack when the pop operation is performed?

• The bottom element is removed

• A new element is added to the top

• The stack is reversed

• The top element is removed

If a stack contains the elements 3, 2, 1 (from top to bottom), what will be the stack's state after one pop operation?

• 1, 3

• 3, 1

• 2, 1

• 3, 2
