Data Structure to Maintain Photographs Database
Your job is to build a data structure to maintain a set of photographs. Your photograph database should allow you to insert and search for photographs, as well as to designate some of the photographs as favourites by marking them. In more detail, your data structure should support the following operations:
Insert(x, t, m): inserts photograph x that was taken at time t. If m = 1, then the...
