Finding the sum of the command-line arguments

Now, let us try something different and tricky: you are going to try to find the summary of the command-line arguments given to your Go program. Therefore, you are going to consider the command-line arguments as numbers. Although the main idea remains the same, the implementation is totally different because you will have to convert your command-line arguments into numbers.
