Remove elements from Array Perl

Question

How to remove matching elements from the array? Let say I have array @A [1, 2, 2, 3, 4, 4, 4, 5] and now I have remove element 2 and 3 so I should see @A [ 1, 4, 4, 4, 5] only in the array.

You can use grep to filter out elements you don't want:

my @A    = (1, 2, 2, 3, 4, 4, 4, 5);
my @newA = grep { $_ != 2 } @A; 
# @newA has elements (1,3,4,4,4,5)

Can I store the modified output in the same array like @A = grep {$_ !=2 } @A ? – user1595858 Nov 25 '13 at 20:31
