FAQs

Question: What is the main difference between arrays and linked lists?
Answer: Arrays have a fixed size and allow random access, while linked lists are dynamic and consist of nodes that point to each other, allowing for efficient insertions and deletions.

Question: How do I analyze the time complexity of an algorithm using arrays?
Answer: You can analyze time complexity by counting the number of operations performed relative to the input size, typically expressed in Big O notation.
