/*

Given a string, return the sum of the digits 0-9 that appear in the string, ignoring all other characters. Return 0 if there are no digits in the string. (Note: Character.isDigit(char) tests if a char is one of the chars '0', '1', .. '9'. Integer.parseInt(string) converts a string to an int.)

sumDigits("aa1bc2d3") → 6

sumDigits("aa11b33") → 8

sumDigits("Chocolate") → 0
