I think this was quite fun, but it can be frustrating if you know nothing about baking cakes, and like needed to re-read instructions a couple of times and think about what happens if you lack some ingredient totally. xD

funny but good! :D

Used TDD and jest for it. Didn't come up with the math clever answer, but was still happy to have used TDD and jest and learned more about that.

Had some repetition that I could refactor away still...

does up and down climbs count equal weight of difference
if starting from 9 -> 8 -> 7 differences would be still = 3 between these?

is it the same as going from 7->8->7 differences would still be 3?

pro (or noob) tips for C++

• remember to forward declare if you intend to use class of your own
• know where to instantiate your object of the class that you need (best practice avoid global variables)
• know the initial state

very clean version using the generic programming! would not have thought this up myself very easily.

what must I do for C++ version of this kata, there is barely any test cases and some comment tells me to create helper object but my code keeps crashing because of that?! I already passed this kata with plain C, but I wanted to see if C++ could be done also...

very nice kata but it was quite simple to "problem-solve" (usually for 6kyu and harder -> they are devilish for problemsolving)
It has been a long time (no pun intended) since I coded Java.

I just used if-else statements and basic math, and maybe two loops to get the time from the input string xD ...
Then I saw that other people used "snappy code" with all kinds of cool Java functions I was awestruck once again
O_o

this was the most confusing kata ever... I still dont know what I was supposed to do even though apparently I succeeded xD
