the predicate given. For example, in the given
example, it tells us that the 2nd, 3rd, 4th elements are equivalent.
And they are equivalent measured by the predicate function given, which
basically tests if their last item are the same integer. (note that if
we want to view the result as indexes, then it is 1-based index. i.e.
counting starts at 1.)
PS if you didn't realize yet, nested lists/dictionaries in perl is a
complete pain in the ass.
PS note that the code "sub {$_[0]->[3] == $_[1]->[3]}" is what's called
the lambda form, in Perl.

Suppose you need to do find and replace of a string pattern, for all

You need to look at it in a case-by-case basis. What can you do?

public static void main(String[] arg) {

System.out.println( x1.str北 );
System.out.println( x1.str★ );
}
}
If you know a lang that does full unicode support, pleas

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

Su
n't a solution.
can this be done in Python?
or, must the args be changed to a list?

Here's the Perl code.

Range($iMax) generates the list [1, 2, ... , $iMax].
Range($iMin, $iMax) generates the list [$iMin, ... , $iMax].
Range($iMin, $iMax, $iStep)
Here's the Python solution.

# implementation note: When iStep is a decimal, rounding error
# accumulates. For example, the last item returned from
# Range(0,18,0.3) is 17.7 not 18. A remedy
e not expected to be exemplary. These
are exercises for all, also as a intro to functional programing to
industry programers. Also, later on there will be non-trivial problems.
