Hello Programmers!!

We, The IIITV Coding Club and Enigma (The IIITV Mathematics Club), are pleased to invite the global competitive programming community to participate in CC × Enigma: Tesseract'26, an online reverse coding contest.

Tesseract'26 is designed to move beyond traditional problem-solving formats and challenge participants through logical deduction, mathematical reasoning, and reverse engineering.

Contest Format
------------------
The problemset will contain around 9-15 problems, each of varying difficulty. The problems will **not** be in any particular difficulty order, so you should attempt all the questions. This contest will be held on [rules of codeforces](https://mirror.codeforces.com/blog/entry/4088).

The contest follows a **reverse coding** format:
- Each problem provides access to an interactive **sandbox** on official website.
- Participants may query the system with custom inputs
- Outputs returned by the system must be analyzed to infer the underlying logic
- No explicit problem statement is provided
- Participants must implement a program that exactly reproduces the observed behavior
- Submissions are evaluated on hidden test cases
- Standard judging rules apply (Accepted / Wrong Answer / Time Limit Exceeded)

Eligibility
------------------
- The contest is open to participants worldwide
- Participation is individual

Prizes Distribution
------------------
**Total Prize Pool : ₹10,000**
**Prize Breakdown**
- Champion: ₹3,300
- Runner Up: ₹2,700
