The beginning and the end

If you want to match something only at the beginning or end of a string, you can use the ^ and $ anchors.

^ - matches the beginning of a string (place it at the beginning of the word e.g. ^word)
$ - matches the end of a string (place it at the end of the word e.g. word$)

Hint: Remember that the | symbol is used to separate alternatives
