Euler Problem 22

My try to solve Project Euler no 22 using Ruby

def get_file_as_string(filename)
  data = ''
  f = File.open(filename, "r") 
  f.each_line do |line|
    data += line
  end
  return data
end

def calc_alpha(alpha)
  ttl = 0
  i = 0
  begin
    ttl += alpha[i].ord - 64
    i += 1
  end until i == alpha.length
  return ttl
end

##### MAIN #####

names_data = get_file_as_string '~\src\euler22\names.txt'

sompret = names_data.gsub('"','')
array = sompret.split(/,/)

array.sort!

running_total = 0

array.each_index do |idx|
  running_total += calc_alpha(array[idx]) * (idx + 1)
end

print 'Result:: '
print running_total
