#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?

total = 0
names = File.open("names.txt", "rb").read.split(',').sort!
names.each_with_index do |name, index|
    sum = 0
    name.each_codepoint {|c| sum += c-64 }
    total += sum * (index + 1)
end
puts total
