[3 1 5 7 0] and [3 2 5 7 0] is similar or not?

'Rows are considered similar if the numbers common to both rows are in the exact same order with no other numbers in between'. Numbers in common are 3, 5, 7. They're in the exact same order. But there is a number in between in both rows, so they're not similar.

Basically, find the numbers that are common to both rows. If they're consecutive in both, with no gaps, keep the row

I see

Maybe a better description for the problem would be that the largest sequence of equal numbers between two rows must have the same size and be unique.

I've added a test to prevent this from working
