Suppose we are given an array [a_1, a_2, ..., a_n] of integers representing the age of users accessing a web-site. Note that each age will always be an integer between 0 and 120. Develop an algorithm that will sort this array in linear time (i.e., O(n)) and using constant storage (i.e., O(1)). Prove that your algorithm is correct and satisfies the efficiency requirements above
