In perl, a/n -------------- is a special character or a sequence that will define the number of times the previous character or sequence appears.

$input = “abdce”; $output = $input =~ s/abc/123; print $input; print $output

splice(@array,-1)

push (@array, @sublist);

unshift (@array, @sublist);

$input = "azz"; print ++$input;

$input = 'abc'; print --$input;

$val = 26; $result = (++$val, $val+5); print $ result;

@array = (1,2,3,4,5) $scalar1, $scalar2 = @array; print “Scalar1 value is $scalar1”; print “Scalar2 value is $scalar2”;

@array= (“one”,”two”,”three”,”four”,”five”); @sublength = (1,2,3); @sub_array = @array[@sublength]; print @sub_array;

$input = “bc999”; print ++$input;

Perl is

. Shifting left n bits, and right n bits, Where n is some number greater than 0 is equivalent to?

/de{3,}/ matches

@array = (1,2); ($scalar1, $scalar2, $scalar3)=@array; print $scalar1, $scalar2, $scalar3;

Is null string list (“”) equivalent to empty list()

Which of the followings can be a pattern delimiter

/abc(?=def)/ matches?
