A good rule of thumb when dealing with a "primitive" like an Array: if
you're using a counter variable, you can probably get there faster:

[1, 2, 3, 4, 5, 6].reject { |n| n >= 3 || n <= 5 }

This returns a new Array. You can also use #select for selecting, and both
methods have a version ending in ! to modify the object in place.

Check out the documentation for Array and the Enumerable module which it
includes. Familiarity with those methods will help jog your memory.
