// Using [names.txt], a 46K text file containing over five-thousand first 
// names, begin by sorting it into alphabetical order. Then working out the 
// alphabetical value for each name, multiply this value by its alphabetical 
// position in the list to obtain a name score.

// For example, when the list is sorted into alphabetical order, COLIN, which is
// worth 3 + 15 + 12 + 9 + 14 = 53, is the 938th name in the list. So, COLIN 
// would obtain a score of 938 × 53 = 49714.

// What is the total of all the name scores in the file?
