Just out of curiosity, which of the following lines match?

The input adheres to n > 0 integers.  There is no previous element to 
compare against so should one assume undefined or 0?  Undefined should 
never be a match, while 0 would be a match only for the first line.  
Perhaps the best solution would be to look for sequences of n > 1?
