Perl:
my $x = 'Apple Carrot Banana';
# sort them into an array
my @y = sort split(' ', $x);
# do we have more than 2 elements? (just a random test)
if (scalar(@y) > 2) {
print "we've got ", scalar(@y), " elements!\n";
print "insufficient elements. fail.\n";
Ruby:
x = 'Apple Carrot Banana'
y = x.split(' ').sort
if (y.size > 2)
puts "we've got #{y.size} elements!"
puts 'insufficient elements. fail.'
Ruby just seems more elegant to me, more programmer-friendly. YMMV.
my $x = 'Apple Carrot Banana';
my @y = $x->split(' ')->sort;
if (@y > 2) {
say "we've got ${\@y->size} elements!";
} else {
say "insufficient elements. fail.";
} use 5.12.2; # enables modern features
my $x = 'Apple Carrot Banana';
my @y = sort split ' ', $x;
say @y > 2 ? "we've got ${\scalar @y} elements!"
: 'insufficient elements. fail.';
One of the reasons I personally like Perl is I can use which ever one is appropriate to the problem domain.
Edit: forgot the `sort` call.
my $x = 'Apple Carrot Banana';
my @y = $x.words.sort;
if @y > 2 {
say "we've got {@y.elems} elements!";
} else {
say "insufficient elements. fail.";
}
