Create a method public String findRepeatedLetters(String word) that will look for repeated letters in word and return those (but only once). So apple would return "p", "cat" would "", "mississippi" would return "isp". "gardener" would return "re"

findRepeatedLetters("apple") → "p"
findRepeatedLetters("cat") → ""
findRepeatedLetters("mississippi") → "isp"

...Save, Compile, Run (ctrl-enter)

public String findRepeatedLetters(String word){ }
