Ek watch hai jisme LEDs se time show hota hai ⏰
Aur tumhe batana hai 👉 kitne LEDs on hone par kaun-kaun se valid times possible hain 😵💫
In this video, we solve Binary Watch (LeetCode 401) using bit manipulation + counting set bits logic — simple, clean, and interview-ready 💯
You’ll learn:
Hours aur minutes ka binary representation
Set bits count ka use
Valid time range kaise check karein
Brute force ko optimize kaise karein
Clean explanation with examples
💡 Quick Challenge:
If turnedOn = 1
Kitne possible times ho sakte hain?
