feat: Generate diamond pattern using nested loops with centered alignment

🧠 Logic:
- Take user input `N` to define the number of rows in the upper half of the diamond.
- First loop builds the top pyramid:
  - Print `N - i` spaces followed by `2*i - 1` stars for each row `i`.
- Second loop builds the inverted bottom pyramid:
  - Iterate from `N-1` down to `1` for symmetric pattern.
  - Print `N - i` spaces followed by `2*i - 1` stars.
- The combination results in a symmetric diamond pattern.

 The diamond is centered, so spaces are used to align the stars.
 The number of stars in each row follows a pattern: 2 * row - 1.
 The number of spaces is calculated as N - row for the upper part and N - row for the lower part.
