+# Lily has a chocolate bar that she wants to share it with Ron for his birthday.
+# Each of the squares has an integer on it.
+# She decides to share a contiguous segment of the bar selected such that the length of the segment
+# mathches Ron's birth month and the sum of the integers on the squares is equal to his birth day.
+# You must determine how many ways she can divide the chocolate.
