# Problem: Find the first ten digits of the sum of the following one-hundred 50-digit numbers.
# Approach: Uh, add them?

import re
if __name__ == "__main__":
    f = open('13.txt','r') # File containing our one-hundred 50-digit numbers.
    numbers = f.readlines()
    
    for i in xrange(len(numbers)):
      re.sub(r'\s', '', numbers[i])
      numbers[i] = long(numbers[i])
      
    sum = 0
    for number in numbers:
      sum += number
      
    print str(sum)[:10]
