Issue #1: A blank name greets nobody

`hello ""` prints `Hello, !`, and `hello "  "` prints `Hello,   !`.

A name that is empty or only whitespace should be treated as no name at all and greet `world`. Surrounding whitespace on a real name should be trimmed.

Add tests for both.

These commands must pass when you are done. Run them if the tools are installed:
- cargo test

Make the change and keep it focused on the issue. Commit your work with a clear message. Do not push; that is done for you. Finish with a short summary of what you changed and why. It becomes the description of your pull request, so write it for a reviewer and leave out whether anything was committed or pushed.

  3. I'll start by exploring the repository structure to understand the codebase.

  4. Bashfind /work/repo -type f -name "*.rs" -o -name "Cargo.toml" | head -20
  5. Read/work/repo
  6. Read/work/repo/src/main.rs
  7. Read/work/repo/src/lib.rs
  8. Read/work/repo/Cargo.toml

  9. Now I understand the issue. The `greeting` function needs to handle empty and whitespace-only names, treating them as "world", and trim surrounding whitespace. Let me fix this:

  10. Edit/work/repo/src/lib.rs

  11. Now let's run the tests to verify the fix works:

  12. Bashcargo test

  13. Let me test the actual command line behavior:

  14. Bashcargo build --quiet && ./target/debug/hello "" && ./target/debug/hello " " && ./target/debug/hello "Ada"

  15. Perfect! Now let me commit this change:

  16. Bashgit add -A && git commit -m "$(cat <<'EOF' Handle empty and whitespace-only names, trim whitespace from input When a name is empty or contains only whitespace, greet 'world' instead of printing "Hello, !" or including the whitespace. Also trim leading/trailing whitespace from valid names. Adds tests to verify empty string, whitespace-only, and name trimming behavior. EOF )"

  17. ## Summary The `greeting` function now properly handles empty and whitespace-only names: - **Empty strings** (e.g., `""`) now greet "world" instead of printing `Hello, !` - **Whitespace-only strings** (e.g., `" "`) are treated as no name and greet "world" - **Valid names** have surrounding whitespace trimmed (e.g., `" Ada "` greets as "Ada") Added three tests to verify this behavior. All tests pass with `cargo test`.
