  • Overlooking the importance of time complexity in evaluating algorithm efficiency
  • Failing to apply real-world scenarios to theoretical concepts
  • Neglecting edge cases in stack and queue operations

FAQs

Question: What are the main differences between stacks and queues?
Answer: Stacks follow the Last In First Out (LIFO) principle, while queues follow the First In First Out (FIFO) principle.

Question: How can I implement a stack using an array?
Answer: A stack can be implemented using an array by maintaining an index to track the top element and using push and pop operations to add or remove elements.
