Hello,

Does someone here knows of an Ada implementation of length-limited Huffman coding ? Basically it is the construction of a Huffman tree with a constraint of a limited tree depth (or code length, if you consider the code formed by walking through the tree). References seem to point to two algorithms [1] and [2] which reduces the memory space needed, compared to [1]. Actually [1] would already be OK for my needs ("Dynamic Deflate" compression in Zip-Ada). 

TIA
