Add Practice Exercise: `transpose`

[0xNeshi]

Problem specification:
https://github.com/exercism/problem-specifications/tree/main/exercises/transpose

TODO:

• generate the exercise with ./bin/fetch-configlet && ./bin/configlet create --practice-exercise transpose
• check if any of the existing tracks (examples below) implement the exercise and you can reuse the implementation:
  • Go: https://github.com/exercism/go/tree/main/exercises/practice
  • Rust: https://github.com/exercism/rust/tree/main/exercises/practice
  • Python: https://github.com/exercism/python/tree/main/exercises/practice
• use exercise's canonical-data.json to see which test cases to implement:

Hello I am really interested to make my contribution but am new to open-source world.

Will be happy to take the task, can anyone just give overview of what is expected? Can assign the task to me

Hi @shreyasgosavi!

Thank you for wanting to contribute to open-source 🚀

This particular issue is already taken, but you're free to pick any of the available ones!

May I suggest one of the easier ones, for example to implement the flatten-array exercise?
If you'd like to work on this, just comment on that (or any other issue) and I'll assign it to you :)

After forking the repository, simply follow the instructions in the issue description and most of the code will be generated for you, which is awesome!

You can take a look at other closed PRs that added existing practice exercises to see what you'll need to do, e.g. this is a good example that implemented isbn-verifier.
You'll only need to implement 3 things:

1. An example solution (example.cairo).
2. A scaffold solution (lib.cairo).
3. Tests ([exercise-name].cairo).

For the example solution, you can use any of the other track's implementations, e.g. for this exercise the Python's implementation is very straightforward!

You'll need to add test cases, for which inputs and expected results are already provided, check out https://github.com/exercism/problem-specifications/blob/main/exercises/flatten-array/canonical-data.json

Make sure to read the README file for instructions on testing, formatting etc.!

Yes. I'm still working on this issue. Apologies it's taking much more time than usual.
