Rohit and Rahul are very close friends, and as Rahul’s birthday
is coming up, Rohit decides to share a chocolate bar with him.
Rohit has made you the in-charge for the sharing of this chocolate.
Each square of the bar has a number written on it,
and Rohit has decided that he will share a
contiguous piece of chocolate, in which the sum of
each number on the squares is equal to the month in which Rahul was
born, and the numbers written on these squares add up to Rahul’s
birth date. You need to find the number of ways the chocolate bar
can be divided.
