Add piecing it together practice exercise

pull request

Add Piecing It Together practice exercise based on the instructions detailed here.

In the config.json file, I included exceptions, for-loops, and if-else-statements as prerequisites. I wasn’t sure whether to add them to the practices array as well, since most exercises seem to leave it empty.

I’ve read the contribution guidelines, but please let me know if I’ve missed anything.

Closes #2949

Thanks! This is a great start!

Leaving the practices array empty is fine!

The only thing missing is the gradle directory. You should simply be able to copy the contents from another exercise, like change (this is needed for students to run ./gradlew properly).

Hello, thank you for your detailed comments! I’ve made the requested changes. I just have one question: I currently placed the JigsawInfo class (previously PartialJigsawInformation) in both .meta/src/reference/java and src/main/java. Is that okay, or was it only needed in the reference folder?

Yes, that's fine! In fact, that's currently needed for the CI tests to pass.

Hi, I’ve updated the builder in the JigsawInfo class and fixed the style issues. The code now passes the verification check. Please let me know if any additional changes are needed.
