Today we'll be writing a function called Range. The Perl documentation
is as follows.

Perl & Python & Java Solutions will be posted in 48 hours.

This is Perl-Python a-day. See

Range

Range($iMax) generates the list [1, 2, ... , $iMax].

Range($iMin, $iMax) generates the list [$iMin, ... , $iMax].

Range($iMin, $iMax, $iStep) uses increment $iStep, with the last
element
in the result being less or equal to $iMax. $iStep cannot be 0. If
$iStep is negative, then the role of $iMin and $iMax are reversed.

If Range fails, 0 is returned.

Example:

Range(5); # returns [1,2,3,4,5]

Range(5,10); # returns [5,6,7,8,9,10]

Range( 5, 7, 0.3); # returns [5, 5.3, 5.6, 5.9, 6.2, 6.5, 6.8]

Range( 5, -4, -2); # returns [5,3,1,-1,-3]
