feat: Print hollow square star pattern using nested loops

🧠 Logic:
- Read integer `n` to define size of the square.
- Use nested loops: outer loop for rows (`i`), inner loop for columns (`j`).
- Print `*` if the current position is on the border:
  - First or last row (`i == 1 || i == n`)
  - First or last column (`j == 1 || j == n`)
- Else, print a space to create the hollow effect inside the square.
