Coding & Algorithms

Given a string s, define the beauty of each letter a–z as a distinct integer between 1 and 26, case-insensitive. The beauty of a string is the sum over letters of (letter beauty × its frequency). Ignore punctuation and spaces. For each input line containing a string, compute and print the maximum possible beauty by choosing an assignment of beauties to letters that maximizes the sum. Examples: Input "ABbCCC" → 152; Input "Ignore punctuation, please :)" → 491.
