# CodeMaster has just returned from shopping. He scanned the check of the items he 
# bought and gave the resulting string to Ratiorg to figure out the total number of purchased items.
# Since Ratiorg is a bot he is definitely going to automate it, so he needs a program
# that sums up all the numbers which appear in the given input.

# Help Ratiorg by writing a function that returns the sum of numbers that appear in the given inputString.
