1. ArrayList

2. encode/decode string
As an example, for the input string "bJbb++b":
         /*     1. 'b' occurs 4 times.
         *       '+' occurs 2 times.
         *       'J' occurs 1 times.
         *    2. Thus, the following encodings are assigned:
         *       'b' -> "1"
         *       '+' -> "01"
         *       'J' -> "001"
         *    3. By concatenating the encodings together, we get:
         *       "10011101011".
