Are multiple alternate solutions acceptable?

@value = "bobcat"

Remove 'bob' from this string in order to return a much tamer version.

Use a non-destructive method to remove 'bob' from this string and return "cat":

>> @value.sub("bob", "")

Not yet...

I would expect any of these (and more) to work:

• @value.sub("bob", "")
• @value.gsub("bob", "")
• @value.tr("bo", "")
• @value[3..-1]
• @value.gsub(/[bo]/, '')
• etc
