To remove an item from an array, you have array#delete(object). But
what you are not doing is using instance variables. If you want
variables to survive as long as your object exists, you must prepend a
'@' to the variable name. And of course, you are missing the
initialization method (called 'initialize'), where instance variables
should be initialized at beginning.

You should go through some elementary-level Ruby tutorial to learn
about these things. If you look at the archive of this list, there
have been several threads where fine tutorials have been mentioned. A
good page to start from is this one, from within Ruby's home page:
