🐛 Refactor Problem Metadata Schema & Remove Hardcoded Problem Details

[kumar-veerendra]

Summary

Refactor the problem metadata system by moving hardcoded values from the frontend into the database schema and ensuring each problem has accurate metadata.

---

Current Behavior

Several problem details are currently hardcoded or use default values instead of being fetched from the database.

Examples:

• Constraints use the same default value for every problem.
• Hidden test case count is hardcoded.
• Hints are hardcoded in the frontend.
• The problem schema does not support storing hints.
• The problem schema does not support hidden test case metadata.

As a result, different problems cannot display their own metadata accurately.

---

Proposed Implementation

Update Problem Schema

Add support for:

• Constraints
• Hints
• Hidden Test Case Count
• Hidden Test Case Metadata (if required)

---

Database Migration

Update existing problems with:

• Correct constraints
• Problem-specific hints
• Hidden test case information

---

Frontend Changes

Remove hardcoded values and fetch metadata directly from the backend.

Replace hardcoded:

• Constraints
• Hints
• Hidden test case count

with dynamic API data.

Current Flow

Open Problem
      │
      ▼
Fetch Problem
      │
      ▼
Frontend injects:
- Default Constraints
- Hardcoded Hints
- Hardcoded Hidden Test Cases

Proposed Flow

Open Problem
      │
      ▼
Fetch Problem
      │
      ▼
Receive Complete Metadata
      │
      ▼
Display:
- Constraints
- Hints
- Hidden Test Cases
- Other Problem Details

Benefits

• Accurate problem information
• Easier to manage problems
• No frontend hardcoding
• Better scalability
• Cleaner architecture
• Easier to add new problems

---

Acceptance Criteria

• Problem schema supports constraints.
• Problem schema supports hints.
• Problem schema supports hidden test case metadata.
• Existing problems are migrated.
• Frontend no longer contains hardcoded values.
• Problem details are fetched dynamically from the backend.
