This brain teaser will develop your programmer's mindset!

If you're a beginner, grappling with this teaser will start rewiring your brain. That’s how it works—if you don’t wrestle with a problem, you don’t get the benefit. So, take this one for a walk in your mind and hopefully experience that satisfying “aha!” moment.

Let’s begin.

👉 How many fingers do you have on one hand? Easy, right?

👉 Now, count the pairs of different fingers. Take your time.

And now, the real challenge:

💡 How many triples of different fingers are there on your hand? But wait! This time, you must answer WITHOUT COUNTING.

Once you have your “aha!” moment, drop a comment explaining how you think this relates to programming—but do your best not to spoil the answer for others!
