stacks_pushIt--Salt and Peppa came out with a hit single in 1987 called "Push it". If you haven't checked out the song, I highly suggest it.

This method takes a String array as a single parameter, and returns a Integer stack.

Iterate through the String array and every index that holds the value of either "Salt" or "Peppa" you should push the index number into the stack to be returned.

If you come across a String value of "Real Good" you should then pop the top value out of the Stack.
