Given 2 strings, a
and b
, return a string of the form short+long+short, with the shorter string on the outside and the longer string on the inside.
The strings will not be the same length, but they may be empty ( zero
length ).
ShortLongShort.solution("1", "22"); // returns "1221"
ShortLongShort.solution("22", "1"); // returns "1221"
