the length of your code is not equal to the code above)

hmmmm...

@dinglemouse it is really nice solution to this Kata. I've come up with 70 lines of code comparing to yours 10

Your algorithm is quite long. its inefficient to say the least.
You could have coded using the arithmetic mathematical formula {val_nth_term = first+c(n)} --> . It makes your life easier

I forgot to remove 'counter' variable in 1st for loop. Its useless

Ok. I get the logic :D

No. The return the only way out of the loop. The while (true) is OK only because a death of a fighter is guaranteed by the rules of this Kata which says initial health and damage values of each fighter are > 0. In other word somebody must die.
