• Names scores

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?

• 例： COLIN
• ソートした場合：リストの938番目にある
• アルファベットの順番： 3 + 15 + 12 + 9 + 14 = 53
• スコア： 938 × 53 = 49714
```\$hash = {"A" => "1", "B" => "2", "C" => "3", "D" => "4", "E" => "5", "F" => "6", "G" => "7", "H" => "8", "I" => "9", "J" => "10", "K" => "11", "L" => "12", "M" => "13", "N" => "14", "O" => "15", "P" => "16", "Q" => "17", "R" => "18", "S" => "19", "T" => "20", "U" => "21", "V" => "22", "W" => "23", "X" => "24", "Y" => "25", "Z" => "26"}

data = Array.new()
File.open("names.txt") do |file|
file.each_line do |numStr|
data = numStr.delete("\"").split(",")
end
end

data.sort!

score = 0
for i in 0..data.length - 1 do
temp = 0
for j in 0..data.length - 1 do
temp += \$hash[data[i][j]].to_i
end
score += (i + 1) * temp
end

p score
```

ハッシュを使わなくても良かったかもしれません．
