We have an array of strings we’d like to later use as hash keys, but we’d rather they be symbols.

1. Create a new variable, symbols, and store an empty array in it.
2. Use .each to iterate over the strings array.
3. For each s in strings, use .to_sym to convert s to a symbol and use .push to add that new symbol to symbols.
4. Print the symbols array.

Check the hint for a refresher on .each and .push.
