Define the function merge_year that aggregates the feeding log data for the given year. Your function definition should not use loops or recursion but use the Python map, reduce, and/or filter functions. You may define and call helper (or anonymous) functions, however your helper functions should not use loops or recursion. You will not get any points if your solution (or helper functions) uses a loop. If you are using reduce, make sure to import it from functools.
