I'm trying to evaluate if a current array matches a preset pair and putting the number of occurrences of the pair in one element of the matrix.
I've tried the following grep statement and it's not working. I think I know why (evaluating to true and false will not increment the counter each time, just replace it), but can someone help me out with what to do instead?
Essentially I want the  element to count how many times AA appears in my input sequence. I have already segmented it up into pairs (hence the @dipept, it only has 2 elements).
As always, I'm just starting out and all help is appreciated. Thankyouu. :)
PS : I'm a little shaky with hashes so if you suggest hashes please do expand on it a little.
