"""
a) The sum of two vectors is just the element-wise sum of their elements.
For example, the sum of [1, 2, 3] and [4, 5, 6] is [5, 7, 9]. Write a function
called sparse_add that takes two sparse vectors stored as dictionaries
and returns a new dictionary representing their sum.

c) It would be useful to automatically “sparsify” a vector. Write a function that called
sparsify that takes in a list of integers and returns a dictionary representing a
sparse vector.
