Guys the problem is like to check if an array is contained inside another array.
perl -le '@x = qw(a b c d e f); @y = qw(a d f); $n = grep { $e = $_; not grep { $e =~ /\Q$_/i } @x } @y; print "Count of elements in (@y) that are NOT present in ( +@x) = $n" ' Count of elements in (a d f) that are NOT present in (a b c d e f) = 0
So if the count is 0, you know that @y is a subset of @x and hence you want to return it from the "induced" subroutine. I hope this would even clear out the mess. Now can this be incorporated as a subroutine. The input will be DATA taken in as an array. The second array will hold the connected components.
____DATA_____ b c a a c d d e b e f g g d f h i g
a b c a b d c e f d g
So I want to see if any row of @DATA is contained inside @Components. So the output expected is
component 1 = a b c induced = b c a component = a b d c induced = b c a a c d component 3 = e f d g induced = e f g g d f
