What are some common mistakes people make with stacks and queues?

Some common mistakes include using a stack when a queue is needed, or forgetting to check if the data structure is empty before popping an element.

Can you give me an example of using a stack incorrectly?

Sure! A common mistake is trying to pop an element from an empty stack, which can lead to errors or exceptions.

What about queues? What mistakes do people make there?

In queues, a frequent mistake is not handling the front and rear pointers correctly, which can cause data loss or incorrect order of elements.

How can I avoid these mistakes?

To avoid these mistakes, always check if the stack or queue is empty before performing operations, and understand the use cases for each data structure.
