The parameter n_args is simply the number of arguments that should be considered

in determining the maximum number. As in:

Three numbers are to be considered: -7, 0 and 8. This way you don't need a

special 'sentinel' value such as -9999 (ugly) to indicate the last argument.

The disadvantage is that you can also do this by mistake:

The number 8 is not considered one of the list for which a maximum must be found.
