Complete the solution so that it takes the object (JavaScript/CoffeeScript) or hash (ruby) passed in and generates a human readable string from its key/value pairs.
The format should be "KEY = VALUE". Each key/value pair should be separated by a comma except for the last pair.
Examples
solution({"a": 1, "b": '2'}) # should return "a = 1,b = 2"
def solution(pairs):
pass
def solution(pairs):
return ",".join(sorted(["{} = {}".format(k,v) for k,v in pairs.items()]))
