Define the function signature, parameter types, and return type. Our generator will auto-create boilerplates for C++, JS, and Rust.

Write the full problem statement in Markdown — examples, constraints, all of it.

# Two Sum

Given an array of integers **nums** and an integer **target**, 
return indices of the two numbers such that they add up to target.

## Examples
```
Input: nums = [2,7,11,15], target = 9
Output: [0,1]
```

## Constraints
- 2 ≤ nums.length ≤ 10⁴

Create a testcases/ folder with numbered .txt files (input and expected output).

testcases/
├── 1.in  → "4\n2 7 11 15\n9"
├── 1.out → "0 1"
├── 2.in  → "3\n3 2 4\n6"
└── 2.out → "1 2"

Use our script to auto-generate boilerplates and validate everything.

# From repo root:
npm run generate --problem=your-problem-slug

# This outputs partial boilerplate (shown to users)
# and full boilerplate (reads stdin, calls your func)
