What are lock-free and wait-free algorithms?

Imagine you and your friends are trying to share one toy, but instead of taking turns politely, everyone grabs it at once! That’s messy. Lock-free and wait-free algorithms help people (or computers) share things smoothly without getting stuck or waiting forever.

Think of lock-free like sharing a cookie jar with your friends. You don’t need to ask for permission, you just take one cookie if there are any left. If someone else is taking a cookie at the same time, that’s okay! It might not always go perfectly, but no one gets stuck waiting forever.

Wait-free is like having a special rule: everyone gets to take a cookie every single time, no matter what. Even if all your friends are trying to grab cookies at once, each of you still gets yours in the end. It’s smoother and more reliable, but it might need a little extra space or rules.

Both help people share things without getting stuck, just like how you and your friends can still have fun with the toy even when there's no one telling you what to do!
