very nice kata, there are at least two approaches to this problem,nice :)

beautiful

RARE PEPE!
great kata!

you are almost there, try debug your code to see where your code is broken (i got stuck on the same issue as well)

c++, got the following error:
-isystem /runner/frameworks/cpp/ error: use of undeclared identifier 'PI'
auto solve = [] (std::vector arr) {
^
what am i missing here?

this kata might be too easy to be a 4kyu kata, but its still super fun, and the solutions here are amazing! thanks:)

this is best practice imo, if the tree has to many nodes recursing can be heavy.

I really enjoyed this :)

Cleaver kata, i was almost tempted to solve it in the trivial way :)

unless the kata will have to deal with other bracket types, this kata is too easy.

C++, Too Easy

c++, Really nice Kata but no assertion for output length. I removed length validation from my solution but i was still able to pass the Kata.

nice kata although a bit to easy for 5 kyu

this kata was fun. i`m not quite proficient in C and struglling was a nice challange , kuddos!

Nice kata
