Elly has two strings of the same length A and B. Now she wants to transform A intoan anagram of B by changing some of its letters.Definition: We call two strings X and Y anagrams of each-other if we can re-arrangethe letters in one of them to get the other.The only operation the girl can make is cyclically increment one or more times some(possibly none or all) of the characters in A. Example increments are 'A' to 'B', 'K' to 'L' or 'Z'to 'A'.For example, she can transform "ELLY" to "KRIS" character by character by shifting 'E'to 'K' (6 operations), 'L' to 'R' (again 6 operations), the second 'L' to 'I' (23 operations, goingfrom 'Z' to 'A' on the 15-th operation), and finally 'Y' to 'S' (20 operations, again cyclicallygoing from 'Z' to 'A' on the 2-nd operation). The total number of operations would be 6 + 6 +23 + 20 = 55. However, to make "ELLY" an anagram of "KRIS" it would be better to change itto "IRSK" with only 29 operations.
