Array Sum

You are given a single line of input containing a list of integers separated by spaces. Your task is to compute the sum of all these integers. If the input is empty or no numbers are provided, you should output 0.

The problem is straightforward: You need to read input from stdin and output the sum to stdout. Handle both positive and negative numbers, and ensure that your solution works even if the input line is empty.
