title: Huffman Code with equal symbol frequencies
body: <p>Starting with these frequencies:</p>
  
  <p>A:7 F:6 H:1 M:2 N:4 U:5</p>
  
  <p>at a later step I have 5 6 7 7, where one of the 7's is the "A". Which 7 branch I pick to be a 0 or a 1 is arbitrary.</p>
  
  <p>So how do I get uniquely decodable code word?</p>
