Write a function that takes in a sequence s and a function fn and returns a dictionary. The values of the dictionary are lists of elements from s. Each element e in a list should be constructed such that fn(e) is the same for all elements in that list. Finally, the key for each value should be fn(e)
def group_by(s, fn):
""" >>> group_by([12, 23, 14, 45], lambda p: p // 10)
{1: [12, 14], 2: [23], 4: [45]}
>>> group_by(range(-3, 4), lambda x: x * x)
{0: [0], 1: [-1, 1], 4: [-2, 2], 9: [-3, 3]}
"""
