Kottans Homework #2 [Enumerable / Comparable / Enumerators]

homework_2.md

Task 1: Comparable

Create a superhero class with the following attributes:

• name
• strength *
• agility *
• intelligence *

You should be able to compare different superheroes based on the avarage of attributes marked with *

Display the list of superheroes sorted by an average, as well as by each of the attributes marked with *

Task 2: Enumerable

You can't deal with everything on your own, that's why a superhero needs a Team.

Implement a Team class which acts as a collection of superheroes so that you can call Enumerable methods on it

Anticipate a situation where no block is provided

Also, create your own enumerable module which implements following methods:

• select
• reduce
• maxmin

Task 3: Enumerators

Construct an infinite list enumerator which would return first n sqaured values(1 < n < 10_000)

Think about an elegant way to implement following methods:

• each_with_object [Note: Yes, I know it's present in the Enumerable. We'd like to see an alternative implementation via different enumerators]
• map_cons
• reverse_cycle_map [Note: without using Array#reverse method]
