Problem: What is the total of all the name scores in the file of first names?

Answer: 871198282

Solution: It was quite easy to implement with LINQ. This goes to show the power of LINQ and the readability of a Functional Program.

var lContent = ReadFile("Problem22.txt");
var lWords = lContent
    .Replace("\"", "")
    .Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

var lNumWords = lWords
    .OrderBy(pArg => pArg)
    .Select((pString, pIndex) =>
            (pIndex + 1) * pString.Sum(pCharArg => pCharArg.ToOrdinal())
    );

var lAnswer = lNumWords.Sum();

Time: 59 ms
