"while ensuring there is exactly one space between each word"

I think you still have cast the float to int somehow

this kata should be evaluated as 8ky somehow

exactly same idea

FYI:
I use the following link http://www.maths.surrey.ac.uk/hosted-sites/R.Knott/Fibonacci/fibmaths.html#section1.1 as reference

man, you are so hard-working....

time complexity would be O(N^3) whish is not optimal

wow

That's true for your code as well! (although thanks for inspiring me to a regex-based solution) Then I noticed You are guaranteed that the number in the passed in string is placed somewhere after the first character of the string. in the description.

you will feel bad if the first character of hero name is digit

merely for logging purpose
