tile_fitting (num_small, num_large, length) Description: You have tiles of two different fixed sizes, 1ft and 5ft long, and you want to decide whether a certain number of these tiles can fit exactly a certain length (we do not care about the other dimension). It's ok if you have more tiles than needed but not the opposite obviously. Parameters: num_small (int) is the amount of the available small tiles (1ft), num_large (int) is the amount of the available large tiles (5ft), and length (int) is the length (in ft) you want to cover. Return value: True if the available tiles can fit exactly the given length and False otherwise.

Suggest a data structure that supports the following operations on the grades that a student at the university receives. Assume that the total number n of exams that the student might take is large. The data structure should support the following operations: (each in O (log n) time, where n is the number of exams taken). (a) insert (exam date, exam-grade). This operation informs the data structure that the student received at date exam date the grade exam-grade. (b) average (datei, datez). As a response to this operation the data structure should answer what is the average of all grades that are received between the dates date and date2. Assume again that all dates are different, and for simplicity, assume that no exam took place in date, nor in date2. Hint: Start by solving the simpler task of being able to report the number of exams that took place between date, to date,
