Problem 393. You LOVES Matlab 41%

Created by Stephen

Given two strings, determine the percentage that one loves the other in the following way:

YOU LOVES MATLAB

there is 1 'L', 1 'O', and 0 of 'V', 'E' and 'S' for the string 'YOUMATLAB' giving 11000. You must add the adjacent digits until you get a two digit 'percentage' as an answer. (if the sum is over 9, add those digits in the next sequence.) 11000>2100>310>41% (the % need not be in the output)

I found this game in an old journal written by a friend when she was 6 years old, testing the compatibility of her older sister with boys in her class.

what do you do when adjacent digits add up to a 2 digit number?

the end rule is also rather unclear, how comes 'humankind loves dinosaurs' goes like ... 1102,212,32; while 'harrypotter loves voldemort' goes like ... 129,311,42. It seems that either the former should end in 33, or the latter should end in 41...

@bmtran (Bryant Tran) on 24 Feb 2012

agreed, i think 'humankind loves dinosaurs' should be 33

Sorry about that. I updated the rules and changed the dinosaur thing. Thank you for point out those errors.

We must compare the frequency of the word 'LOVES' with the word concatenation upper([E,S]) if someone else finds the problem description unclear. And [9,9,9] must become [1,8,1,8], which is also not clear by the description. Notice that this would create an infinite loop, but that's the current solution for this problem.

PS: My first guess was that [9,9,9] should become [1,2,2,6] -> [3,4,1,0] -> [7,5,1]-> 1 8 %, which makes more sense than some cases generating an infinite loop.
