Solution

To create an optimal Huffman code, we need to follow these steps:

  1. Create a frequency table:

    • Count the frequency of each symbol in the given data.
    • In this case, the frequency table would be:
      • a: 1
      • b: 1
      • c: 2
      • d: 3
      • e: 5
      • f: 8
      • g: 13
      • h: 21
  2. Create a priority queue:

    • Initialize a priority queue with the symbols and their frequencies.
    • The priority queue will be sorted based on the frequencies.
    • In this case, the priority queue would be:
      • a: 1
      • b: 1
      • c: 2
      • d: 3
      • e: 5
      • f: 8
      • g: 13
      • h: 21
  3. Build the Huffman tree:

    • Take the two symbols with the lowest frequencies from the priority queue.
    • Create a new node with a combined frequency equal to the sum of the two symbols' frequencies.
    • Make the two symbols as the left and right children of the new node.
    • Insert the new node back into the priority queue.
    • Repeat these steps until there is only one node left in the priority queue, which will be the root of the Huffman tree.
    • In this case, the Huffman tree would be: _________ /
      h: 21 _________ /
      g: 13 _________ /
      f: 8 _________ /
      e: 5 _________ /
      d: 3 _________ /
      c: 2 _________ /
      a: 1 b: 1
  4. Assign binary codes:

    • Traverse the Huffman tree from the root to each leaf node.
    • Assign a '0' for each left branch and a '1' for each right branch.
    • The binary codes for each symbol would be:
      • a: 1111111
      • b: 1111110
      • c: 111110
      • d: 11110
      • e: 1110
      • f: 110
      • g: 10
      • h: 0

Therefore, the optimal Huffman code for the given symbols and frequencies would be:

  • a: 1111111
  • b: 1111110
  • c: 111110
  • d: 11110
  • e: 1110
  • f: 110
  • g: 10
  • h: 0
