Stack Data Structure Quiz

Stacks and Queues

• A stack is also known as Last In First Out (LIFO).
• Removing an element from an empty stack is called Underflow.
• The order of removal in a stack is Last In First Out (LIFO).
• Elements in a stack are removed in the reverse order they were added.

Data Structures

• A tuple is an immutable data structure.
• A list is a mutable data structure.
• A list in Python is created using square brackets [].

Functions and Lists in Python

• The keyword def is used to define functions in Python.
• To get the second element in a list called "bus", use bus[1].
• The append() method is used to add an element to a list (or stack).

Stacks and Queues (continued)

• Inserting an item into a stack when it's not full is called a Push operation.
• Deleting an item from a stack when it's not empty is called a Pop operation.
• A queue follows the First In First Out (FIFO) principle.

Postfix Expressions and Palindromes

• The expression abc*+de-+ is an example of a postfix expression.
• A stack is used to test a palindrome.

Data Structures (continued)

• A linked list is a sequence of data elements connected to each other.
• A graph is a non-linear data structure.

Stacks (continued)

• The Peek() function returns the top data element of the stack.
• The Push() operation inserts an element into a stack.
• The Pop() operation deletes an element from a stack.

Algorithms

• An algorithm should have unambiguous, feasible, and definite steps.
• The effectiveness of an algorithm is a measure of its performance.

Algorithm Analysis

• The running time of an algorithm can vary with the computer's processor speed.
• The number of statements in an algorithm can vary with the programming language and programmer's style.
• The best case is when the running time of an algorithm is the shortest.
• The average case is when the running time of an algorithm falls between the worst and best cases.
• Pseudocode is a compact, informal, and environment-independent description of a computer programming algorithm.

Recursion

• A stack is used to perform recursion.
