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.

Why inner join?

This answer return new string. I thought the problem stated that "returns the same string with all even indexed characters in each word upper cased, and all odd indexed characters in each word lower cased."
Bro, I tried the same thing but they showed me error! donno why!
I used a really long winded recursion implementation and I feel so stupid looking at this
Yeah, that = is pointless
semi colons in sql are just query separtors, if it's one query it's fine
How do you guys solve such problems? Just interesting, do you google for a formula and build an algorithm based on the formula or you just trying to recreate the formula by yourself?

I was really struggling with the iterative solution, but this is so cool.
I wonder why when I change (principal, interest, tax, desired) by (p, i, t, d) do I get 3.92 instead of 1, when I try to pass calculate_years(1000,0.01625,0.18,1001)...
Am I missing something here?

I guess it would have to be changed because if there is some other column that gets added to the table, then we would have to update the query and select the newly added column as well.
If we use select ALL(select * ) we won't have to edit the query, as it selects all the columns there are to select.
