Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

Depends on what you compare. If indeed you compare it to 7 kyu fibonacci, then yeah, you aren't gonna use the exact code again. However fibonacci gives you knowledge of recursion and perhaps cacheing. Also, if you look at 3-4 kyu tasks, you notice some even make you program some part of a game.
Thank you for this kata, it was a tough one but very instructional! Learned how to apply CTEs instead of casting a column a bunch of times.
That was a tricky one! Thank you for this kata, learned a lot!

Hi people,
When I do the test I got an error message, but my results are exaclty the expected answers... do you know why?
I have: log 15 ! None should equal 15
and so on for all tests...
Very good kata! After having failed one of the test, I realized that the answer was in this part of the instructions:
"(** number of inhabitants is an integer **)"
Thank you for this kata. It was a good lesson on how not to unnecessarily start joining tables and grouping results. As I thought, the answer was quite straightforward (with the obvious exception of the median calculation, which was a new thing to me).
Thank you for this kata. It was a nice way to see how other people have dealt with the challenge!
Thank you for this kata. It is always challenging to deal with float numbers and decimal points in POSTGRES. It took me a while to finally round the numbers while casting them as float types.
Good kata, thank you!
This is the kind of kata that I really like to solve. They look like real life challenges (well, I don't think I'll be finding the nth value of a fibonacci sequence anytime soon during work!). Thank you!
In this case, lower() will lower all first letters. It is a way to make words case insensitive, as all Rs will be converted to r, thus having no need to check for differences.
Veru good challenge. The instructions were clear and it was a good way to practice working with different dtypes and converting them accordingly. Thank you!
