Discussion about LZW and Huffman code

Is there an input for which Huffman coding will produce the optimal compression (i.e., the cost will match the entropy)?

Suggest an input on which compression ratio for Lempel-Ziv Welch (LZW) algorithm will be better than for Huffman coding.

Suggest an input on which compression ratio for Huffman coding will be better than for Lempel-Ziv Welch (LZW) algorithm.

What are the main differences between these algorithms? What if we use Huffman on the LZW result?
