Classic computer architecture experiment: Iterate over 100,000 integers and conditionally sum elements > 128. If the array is unsorted, the CPU's branch predictor misses 50% of the time, stalling the instruction pipeline. If the array is sorted, branch prediction accuracy is ~99%, and execution runs 6x faster. Understanding hardware mechanics makes you a dramatically better programmer.

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

Eating healthy in college without spending ₹4,000 on whey protein powder every month: 1. 4 boiled eggs from the campus cart (₹30 total = 24g protein) 2. 100g roasted chana / sattu drink in the morning (20g protein) 3. Double serving of dal / paneer / chicken on mess days (25g protein) 4. 500ml milk with oats at night (16g protein). Cheap, sustainable, and hits your daily macronutrient target.

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.

1. The 3-5 close friends who will pick up your call at 3 AM ten years from now. 2. The ability to learn a completely new domain from scratch in two weeks without getting overwhelmed. 3. Your health, emotional resilience, and communication skills. Keep your GPA above the eligibility cutoff (usually 7.5 or 8.0), but don't sacrifice your youth and friendships chasing a 9.8.
