Class Method Details

.call(output: $stdout, arguments: ARGV) ⇒ Object

Generates a multiplication table of the first N primes (specified by a command line argument by default) and outputs it to the specified output (‘STDOUT by default).

Parameters:

  • output (IO) (defaults to: $stdout) —

    the output to print the table to

  • arguments (Array) (defaults to: ARGV) —

    the CLI arguments (where the first argument is expected to contain the number of primes to use, starting from zero)
