Sum of Odd Digits

Given an integer (n), compute the sum of all odd digits present in (n). Note that (n) may be negative; in such cases, the sign is ignored. For example, if (n = 123456), then the odd digits are 1, 3, and 5, and their sum is 9. Your task is to write a program that reads an integer from standard input, calculates the sum of its odd digits, and writes the result to standard output.
