feat: Mirror a string by concatenating it with itself for multiple test cases

🧠 Logic:
- Read the number of test cases `t`.
- For each test case:
  - Read a string `s`.
  - Create a new string `x` by concatenating `s + s`.
  - Print `x`.

📌 Purpose:
Demonstrates string manipulation using concatenation in Java and looping through multiple inputs efficiently.
