When you're trying to choose between a stack and a queue, it really depends on how you want to work with your data. Let’s look at some situations where a stack is a better choice:
Last-In, First-Out (LIFO): If you need the last thing you added, a stack is what you want. Think about the "undo" button in a text editor. You want to undo the last action first, right?
Recursion: Stacks are super useful when a function calls itself. Each time this happens, it saves the previous step in a stack. When the function is done, it goes back to where it was before.
Backtracking: If you’re solving a maze, stacks help you remember the paths you've taken. This way, if you reach a dead end, you can easily backtrack to try another way.
Expression Evaluation: In programming, stacks help read expressions. They are especially important when changing the way we write expressions, like from normal to postfix.
On the other hand, if you want things to be handled in the order they arrive, like waiting in line, then you should use a queue.
So, if you need to quickly access your latest data, choose a stack!
