Python 3, Thank you.

Write a function named rarest age that accepts as a parameter a dictionary from students' names (strings) to their ages (integers), and returns the least frequently occurring age. Consider a dictionary variable named m containing the following key/value pairs CChar': 45, 'Dan': 45, 'Jerry 23, 'Kasey' 10, 'Jeff': 18, 'Elmer': 45, 'Kim': 1, 'Ryan': 45, 'Mehran' 23) Three people are age 10 (Kasey, Jeff, and Kim), two people are age 23 (Jerry and Mehran), and four people are age 45 (Char, Dan, Elmer, and Ryan). So a call of rarest age(m) returns 23 because only two people are that age If there is a tie (two or more rarest ages that occur the same number of times), return the youngest age among them. For example, if we added another pair of Steve: 23 to the dictionary above, there would now be a tie of three people of age 10 (Kasey, Jeff, Kim) and three people of age 23 (Jerry, Mehran, Steve) So a call of rarest age (m) would now return 10 because 10 is the smaller of the rarest values. This implies that if every person in the dictionary has a unique age, your function would return the smallest of all the ages in the dictionary If the dictionary passed to your function is None or empty, your function should return B. You may assume that no key or value stored in the dictionary is None Otherwise you should not make any assumptions about the number of key/value pairs in the dictionary or the range of possible ages that could be in the dictionary Constraints: You may create one collection of your choice as auxiliary storage to solve this problem. You can have as many simple variables as you like. You should not modify the contents of the dictionary passed to your function
