Huffpuff

spbctf

Task: 64-bit ELF that computes custom Huffman codes for a fixed internal string and prints only code integers plus the encoded bitstream. Solution: reverse the exact heap tie-breaking and bit-building logic, reconstruct a consistent prefix code table, then decode the stream into the final sentence.
