Endsem aane waale hai 😢 Please koi thoda guide kardo, CG mere bas sai bahar hoti jaa rhi hai 😭 Lagta hai coding sai break Lena hi hoga 😭


Day 56 & 57 – #100DaysOfCode Recursion + OOP combo 😵‍💫 • Printed binary numbers where 1s >= 0s • Started OOP – made Bank, Car & Laptop classes (OOP vibe 🔥) • LeetCode revision: Max Product of Word Lengths • POTD: Laser Beams in a Bank DSA grind mode ✅ #CPlusPlus #DSA

"This is a glimpse of my latest documentary exposing the ground reality of Bihar’s health infrastructure. What I witnessed inside hospitals was shocking — beyond words. A system meant to save lives is itself struggling to survive. Full Video on YT youtu.be/wBq9Egu_Cls?si…


Day 54 & 55 – #100DaysOfCode Aaj recursion ne literally dimaag ghumaya 😂 • Josephus Problem – last banda bachaane ka logic 🔄 • Rat in a Maze – backtracking ka asli maza 🧠 • LeetCode POTD for cooldown: Calculate Money in Bank 💰 Code kam, dimaag zyada laga.

Tower of Hanoi today… and recursion just flexed on my brain 🧠🔥 Day 53 – #100DaysOfCode You don’t manually move N disks — you trust recursion to move N−1 and everything starts falling into place. This problem doesn’t test coding. It tests how you think. #Recursion

Recursion ka real secret aaj samjha👇 Don’t jump into code. First think mathematically, then structure the flow, then build recursion tree, and only then touch the keyboard. Day 52 – #100DaysOfCode Solved: Permutation II, Ways to Sum N, Combination II, Elimination Game

Day 51 – #100DaysOfCode Recursion + Permutations = pure brain workout 🧠🔥 Array→Lecture que. String → absolute chaos 😂 (multiple wrong attempts, countless dry runs) Abhi bhi lag rha hia kuch to rh gya samajhna 😅 Some days you don’t solve recursion… recursion solves YOU.

Day 50 – #100DaysOfCode TLE mil gaya 💀 But kya seekhne ko mila, bata nahi sakta 😮‍💨 Aaj do monsters tackle kiye 👇 • Subset with sum divisible by m • Subsequences of string divisible by n Dono ne TLE diya (as expected 😅) but logic aur recursive flow next level pe samajha🔥

💫 Recursion × Subset Magic day 49 – #100DaysOfCode subsets & their sums recursion se generate karna sikha 🔁 logic simple tha: lena hai ya nahi lena 👀 HW: • subset sums • print subset + sum • perfect sum (TLE on last 2 😭 tried zero freq optimization but still stuck 💀)

No coding progress today 😔 Aaj ek college coding soc ka recruitment tha and kal file submission + viva hai ECE ka 😭😭 Couldn't manage to code 2day, since bhot hectic din tha


😵‍💫 Aaj recursion ne dimaag hila diya! day 48 – #100DaysOfCode “Recursion on subsequences” padha 🔁 Socha easy hoga, par function flow ne maze le liye 💀 HW: print all possible sums from subsequences jab finally output aaya → pure satisfaction 💯
