@array = (1 2 3 4 5 6 7 8 10 14 15 20, 7 14 20, 21 22 23 24 40 50);

This is not valid Perl code. Should that be three strings? Or three array references?

I want to combine the elements

How do you want to combine them? concatenate? Or sort numerically, and remove duplicates?

How do I merge two elements if all the elements of one element are present in other as in 0th and first element?

How are we supposed to know what your requirements are?

Also, what have you tried so far?
