prev  |  next  |  chance

Given a string, take the last char and return a new string with the last char added at the front and back, so "cat" yields "tcatt". The original string will be length 1 or more.


backAround("cat") → "tcatt"
backAround("Hello") → "oHelloo"
backAround("a") → "aaa"

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

public String backAround(String str) { }
