Question: 'Estimate the number of cups of tea consumed daily on your university campus.' 1. State clarifying assumptions (campus student population = 6,000; hosteler vs day scholar split = 80/20). 2. Segment by user personas (non-tea drinkers = 30%, light drinkers = 1 cup/day, heavy exam grinders = 3 cups/day). 3. Add faculty and canteen footfall. 4. Sanity check with canteen vendor batch sizes. Interviewers care about structured logic, not the exact number.

Variables are what is inside the locker. A pointer is simply a slip of paper with the locker number written on it. The `&` operator gives you the locker number. The `*` operator opens the locker and reads what is inside. That's literally the whole concept. Don't let your first C programming textbook intimidate you.

At least 6 passport-size photos and 10 photocopies of Aadhaar/12th marksheet 6. First-aid pouch with paracetamol, antacids, and band-aids. Save this post!

I can’t take it anymore. People outside think NIT Warangal is a top-3, Tier-1 institute, but living here is an absolute nightmare. 1. Basic Infrastructure Failures (No tables, no chairs, broken toilets) No Basic Amenities: We haven't even been provided basic study tables and chairs in our hostel rooms. How is a student supposed to study or sit comfortably in their own room? Sanitation Crisis: The hostel toilets are biohazards. Flushes don't work, jet sprays are completely broken, a

Started with dead hangs (building grip strength for 45s), then moved to eccentric negatives (jumping to the top bar and lowering over 5 seconds), then resistance bands. Once you hit 3 clean reps, do 5 sets every alternate day. The hostel corridor pull-up bar is the best gym equipment you will ever need.
