Can results of the Huffman code always be different? I have to construct the Huffman code for this;

But I am seeing conflicting things, for example;

1(242) being 1010 in Huffman code

1(242) being 0100 in Huffman code

1(242) being 0101 in Huffman code.

I'm super confused!

Thank for clarification

1. A file contains only colons, spaces, newlines, commas, and digits in the following frequency: c space (605) newline (100), comma 705), 0 (431), 1 (242, 2 (176, 3 (59), 4 (185), 5 (250), 6 (174), 7 (199), 8 (205), 9 (217) Construct the Huffman code
