Valid Huffman Codes?
<p>I'm trying to solve a Huffman Coding problem, but I'm not completely sure I understand the topic completely. I am trying to figure out if the following are is a valid Huffman Code:</p>

<pre><code>A: 0  
B: 01  
C: 11  
D: 110  
E: 111  
</code></pre>

<p>What I'm thinking is that it is not valid, because A, or 1, would infringe on B, or 01. I'm not positive though. Could someone enlighten me on this?</p>

<p>Edit: I'm sorry I meant to type A as 0 and not 1.</p>
