Language/Type: C++ Map Set Vector collections
Author: Marty Stepp (on 2016/06/29)

Write a function named reverse that accepts as a parameter a reference to a map from integers to strings, and returns a map with the associations reversed. For example, if a variable named map stores the following key/value pairs:

{1:"a", 2:"b", 3:"c"}

the call of reverse(map); would return the following map:

would yield
{"a":1, "b":2, "c":3}

If there are duplicate values (k1, v) and (k2, v) in the original map, your returned map should contain the pair that would come earlier in sorted order.
