The basic idea is you want to pull each letter out of any given phrase and print in every line. So you want to use a for loop to do that. To get a letter out, you can you string class method substring to print it. So you want an index1 and index2 to get the letter you want. You can start with 0 and end with the index of the last letter, which you could get by finding the length of the entire phrase.
