How are we suppose to know each block takes how many height. The test only give us the so called height, m

Ah, I should've saw that. That was my bad, thanks for pointing out :)

It's hard to tell from the error message, but I can see in your code it will result in an unwanted trailing whitespace.

this solution will get execution timed out

This is an issue with this kata.

It doesn't support anonymous functions. Try and use the function cleanString () {} notation instead.

The author did not mention that the input check amount has to be in 2 decimal places. I was suppose to pass all of the tests much sooner but instead spending my time copy and pasting stuff into diffchecker to figure it out. I should've read the comment earlier so I don't have to go through these mess. Even after comments regarding this, the author has yet to improvise the description for this matter.
Overall a good kata but terrible description once again by @g964.

Same problem right here..

One of the very fun kata that I've worked with so far! Thanks @lambda4fun

.

If you still have troubles, try looking what the bounds are of the numbers that should be exponentiated

Thank you very much @gnemlock

As usual, this particular user's description is just poor. What a surprise

@Ciprian Amza

It's not even about solving the kata. I couldn't get my head around what the description wanted me to do, let alone solving the kata.

Usually, we one can't solve a kata, he tends to think that the kata is the problem. But we should just get better, it's normal to not be able to solve all of them.

Description modified. No offense to anybody and no arrogance but I could not have imagined that one try coding without a bit of mathematical vocabulary knowledge and/or research.
