front22

/*Given a string, take the first 2 chars and return the string with the 2 chars added at both the front and back,
so "kitten" yields"kikittenki". If the string length is less than 2, use whatever chars are there.
front22("kitten") → "kikittenki"
front22("Ha") → "HaHaHa"
front22("abc") → "ababcab"
