I think the decision "symbol or string" is not what you
should be concerned about right now, it's a subtlety.
Both would work fine for you for the time being.

There are other problems:

Have you actually tried that? It cannot work for a string `value'.

1. You want numbers:

    "0a" & 1
    NoMethodError: undefined method `&' for "0a":String

    5 & 1
      # => 1

    6 & 1
      # => 0

2. Your condition is *always* true:

    puts "true!"  if 6 & 1
      # true!

    (Note: in Ruby, 0 is true!)

So, do not get distracted by subtleties like symbols, but concentrate
on learning some Ruby basics and getting your program to work.

Regards,
Marcus
