# Using names.txt (right click and 'Save Link/Target As...'), 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?
