Crack the Pattern

A one-month daily batch that makes hard coding problems easy. It starts from the fundamentals so nobody is left behind, then teaches the handful of patterns behind LeetCode-style problems, each one felt on a simulation, then written and run against real tests in an in-browser editor.

What is Crack the Pattern?

A one-month daily batch that makes hard coding problems easy. It starts from the fundamentals so nobody is left behind, then teaches the handful of patterns behind LeetCode-style interview problems.

Do I need to know coding already?

No. A short Day Zero takes you from never-coded to your first list and loop, then you join the batch on the same footing. School maths and steady daily attendance are enough.

Why learn it here?

Because you feel each pattern on a simulation first, then write and run it against real tests in the browser, and finish by proving it in a live mock interview. Real practice, not lectures.

What you will do

  • Start from zero

    The first sessions take you from never-coded to your first working program.

  • Read any problem

    The four questions that make a scary problem clear.

  • One pattern a day

    The handful of patterns behind two pointers, windows, recursion, graphs, and dynamic programming.

  • Feel it first

    See each idea move on a simulation before you write a line.

  • Solve it for real

    Write your solution and run it against real tests in the browser.

  • Prove it live

    Finish with a live mock interview and a verifiable certificate, not a family show.

What you will be able to do

  • Read any coding problem calmly, with four simple questions
  • Recognise and apply the patterns behind LeetCode-style problems
  • Write your solution and run it against real tests in the browser
  • Prove it live in a mock interview, and explain your thinking

You walk out with a pattern playbook and a verifiable certificate.

Your journey, step by step

13 steps, from the very first day to a real skill, ending in Interview Day.

Start here
  1. 1
    Get coding

    The first days take you from never-coded to your first working loop.

  2. 2
    Read any problem

    The four questions that make a scary problem calm.

  3. 3
    Arrays and hashing

    The shelf and the magic notebook, the two you use most.

Build it up
  1. 4
    Two pointers and windows

    Walk a list from both ends, and slide a window along it.

  2. 5
    Sorting and binary search

    Put things in order, then find them by halving.

  3. 6
    Stacks and queues

    The plate pile and the fair line, and where each one wins.

  4. 7
    Recursion

    A problem that solves smaller copies of itself.

  5. 8
    Trees

    Branching data, and the three ways to walk it.

Go further
  1. 9
    Graphs, wide and deep

    Maps of connections, explored by breadth and by depth.

  2. 10
    Shortest paths and groups

    The cheapest route, and joining things into sets (union-find).

  3. 11
    Dynamic programming

    Remember what you solved so you never redo it. The one that separates offers.

  4. 12
    Greedy and the rest

    When the quick choice is safe, and the last few patterns.

The big day
  1. Interview Day

    Prove it in a live mock interview and take home your playbook and certificate.

Why this is different

From zero: a short Day Zero takes a never-coder to a first working loop
Feel each pattern on a simulation, then solve it for real against hidden tests
An in-browser editor with a real compiler; nothing to install
Ends in a live mock interview before invited engineers, not a family show

Pick a time and book

Every weekday (Monday to Friday), 6:00 to 8:00 PM

24 sessions, the last is Interview Day.

Interview Day

On the final day each student proves it in a live mock interview, and takes home a verifiable certificate and their own pattern playbook.

How to join, in three steps

  1. Pick a time above and reserve a seat.
  2. Pay Rs 4,050 by cash or UPI at the Lab and take your GST receipt.
  3. Come to the Lab. We email a 6-digit code to check in.

New to coding is welcome; a short Day Zero takes you from zero to your first loop. A GST receipt is issued at the Lab; pay by cash or UPI.

Small group of 10. For students stepping into engineering, and anyone new to coding who is ready to work.

Every learner finishes with a certificate anyone can verify.

The honest bit

You leave able to read and solve interview-style problems, with a pattern playbook and a verifiable certificate. We do not promise jobs or offers; we promise the skill and the proof you build in the room, shown live on Interview Day.

"LeetCode-style" describes a kind of problem; we are not affiliated with LeetCode.
