I'd say it would be an actual 6 kyu if it required you to do it in O(1)

Seems like you've solved it! But you missed this part of the description --> Any characters in a MiniStringFuck program other than + or . are simply non-command characters (no-ops, i.e. do nothing) and therefore can serve as comments in the program.

python new test framework is required. updated in this fork

thank you dude

Because you need to return the first n rows. The first row is 1, the second row is 1,1, so for n = 2, you need to return both rows: [1, 1,1]

it was a nice one
but i'm confused as to why when n=2 it has to return [1,1,1] not [1,1]

Four words: Set, add, delete, Array.from.

Please don't make a ( horribly underspecified ) task out of reimplementing Set, including insertion order even.

The kata seems to be during the state of being fixed of critical issues: sample tests are not using test framework; specs are missing (throwing an error requires a specific message that isn't mentioned at all, and nothing is mentioned about "empty tasks". And why mark_done also accepts a numeric index?), and no random tests.

Please only publish a kata once it's ready for beta process.

Despite being categorized as a 6kyu-level challenge, the task at hand appears to be relatively straightforward, requiring a level of proficiency that aligns with the lower end of the difficulty spectrum for coding exercises.
Stay Hard

yup agree
