Code Table

If only one single node is remaining within the table, it forms the root of the Huffman tree. The paths from the root node to the leaf nodes define the code word used for the corresponding symbol:

   Symbol   Frequency   Code Word
       a      5          0
       b      2          10
       r      2          111
       c      1          1101
       d      1          1100
