Given a list of pairs of spans (of the form a-b,x-y) count how many spans have one span entirely contained within the other.
Take a list of characters. For each line, split the line exactly in half and find the one character that’s in both halves. Assign a-z to values 1-26 and A-Z to 27-52. Sum these values.
