Create a function that takes a string and returns a new string with its first and last characters swapped, except under two conditions: 1. If the length of the string is less than two, return "Incompatible." 2. If the first and last characters are the same, return "Two's a pair." Examples flipEndChars ("Cat, dog, and mouse.") → ".at, dog, and mouseC" flipEndChars ("ada") → "Two's a pair." flipEndChars ("Ada") → "ada" flipEndChars("z") "Incompatible."
