Key Takeaways: When range is small → HashSet + loop is clean & fast When range is huge → sorting + adjacent diff might be better Always use min/max given in problem (they exist!) What’s your favorite way to solve this? HashSet or sort? #Array #HashSet

Sharp • Developer-friendly • Quick insight HashSet in Java is simple: ✨ Unique items only 🚫 No duplicates allowed If the value already exists, Java quietly ignores it. Clean data, clean logic. Learn Java the visual way 👇 crackease.comOg6 #Java #HashSzAd
