Sum of Odd Numbers

You are given a sequence of integers. Your task is to filter out all even numbers and then sum all the odd numbers. An integer \( x \) is odd if \( x \mod 2 \neq 0 \). If there are no odd numbers, the sum is considered to be 0.

For example, given the input 1 3 5 7, the output should be 16 because \(1+3+5+7=16\).

Read the input from standard input and write the result to standard output.
