You don't have to write code to contribute
Some solutions have short or missing explanations. Help the next learner understand them.
Time: ~5 minutes | Skills needed: Reading + writing
Task
- Pick any solution file (any language)
- Read it
- Improve the top comment: what does it do, in simple words?

Only edit comments, please don't change the code.
Explaining code is one of the fastest ways to understand it.
Comment which file you picked.

Hi, I'd like to work on this. I'll pick one solution and add a plain-English explanation. Is that okay?

Thank you for the green light! Done. I picked solutions/python/practice10.py "First Letter to Appear Twice" and added a plain english explanation to the top comment. Only comments changed, noo code. PR: #229
