removeEvens

Language/Type: Java Sets and Maps
Author: Marty Stepp (on 2020/10/22)

Write a method removeEvens that takes a set of integers as a parameter and that removes the even values from the set, returning those values as a new set. The new set should be ordered in increasing numerical order. For example, if a set s1 contains these values: 

[0, 17, 16, 7, 10, 12, 13, 14]

and we make the following call: 

Set s2 = removeEvens(s1);

Then after the call s1 and s2 would contain the following values: 

s1: [17, 7, 13]
s2: [0, 10, 12, 14, 16]
