Beautiful Strings | |
When John was a little kid he didn't have much to do. There was no internet, no Facebook, | |
and no programs to hack on. So he did the only thing he could... he evaluated the beauty | |
of strings in a quest to discover the most beautiful string in the world. | |
Given a string s, little Johnny defined the beauty of the string as the sum of the beauty | |
of the letters in it. | |
The beauty of each letter is an integer between 1 and 26, inclusive, and no two letters | |
have the same beauty. Johnny doesn't care about whether letters are uppercase or lowercase, | |
so that doesn't affect the beauty of a letter. | |
(Uppercase 'F' is exactly as beautiful as lowercase 'f', for example.) | |
You're a student writing a report on the youth of this famous hacker. You found the string | |
that Johnny considered most beautiful. What is the maximum possible beauty of this string? | |
Input | |
The input file consists of a single integer m followed by m lines. | |
Output | |
Your output should consist of, for each test case, a line containing the string "Case #x: y" | |
where x is the case number (with 1 being the first case in the input file, 2 being the second, etc.) | |
and y is the maximum beauty for that test case. | |
Constraints | |
5 <= m <= 50 | |
2 <= length of s <= 500 | |
Example input Example output | |
5 | |
ABbCcc Case #1: 152 | |
Good luck in the Facebook Hacker Cup this year! Case #2: 754 | |
Ignore punctuation, please :) Case #3: 491 | |
Sometimes test cases are hard to make up. Case #4: 729 | |
So I just go consult Professor Dalves Case #5: 646 | |
