This regex challenge definitely gave me a headache at first! It felt like trying to climb a really steep and confusing trail where every step needs careful thought. Luckily, I recently took a break and did the Langtang Valley Trek in Nepal — a peaceful escape with stunning mountain views and quiet trails that really helped clear my mind. Coming back from that kind of reset made tackling tricky problems like this feel much more manageable. Sometimes stepping away is exactly what you need to solve the toughest challenges.
