The sorted table is work[], with that space being provided by\n the caller.\n The length counts are used for other purposes as well, i.e. finding\n the minimum and maximum length codes, determining if there are any\n codes at all, checking for a valid set of lengths, and looking ahead\n at length counts to determine sub-table sizes when building the\n decoding tables.\n */\n\n /* accumulate lengths for codes (assumes lens[] all in 0..MAXBITS) */\n\n for (len = 0; len <= MAXBITS; len++) {\n count[len] = 0;\n }\n\n for (sym = 0; sym < codes; sym++) {\n count[lens[lens_index + sym]]++;\n }\n /* bound code lengths, force root to be within code lengths */\n\n\n root = bits;\n\n for (max = MAXBITS; max >= 1; max--) {\n if (count[max] !== 0) {\n break;\n }\n }\n\n if (root > max) {\n root = max;\n }\n\n if (max === 0) {\n /* no symbols to code at all */\n //table.op[opts.table_index] = 64; //here.op = (var char)64; /* invalid code marker */\n //table.bits[opts.table_index] = 1; //here.bits = (var char)1;\n //table.val[opts.table_index++] = 0; //here.val = (var short)0;\n table[table_index++] = 1 << 24 | 64 << 16 | 0; //table.op[opts.table_index] = 64;\n //table.bits[opts.table_index] = 1;\n //table.val[opts.table_index++] = 0;\n\n table[table_index++] = 1 << 24 | 64 << 16 | 0;\n opts.bits = 1;\n return 0;\n /* no symbols, but wait for decoding to report error */\n }\n\n for (min = 1; min < max; min++) {\n if (count[min] !== 0) {\n break;\n }\n }\n\n if (root < min) {\n root = min;\n }\n /* check for an over-subscribed or incomplete set of lengths */\n\n\n left = 1;\n\n for (len = 1; len <= MAXBITS; len++) {\n left <<= 1;\n left -= count[len];\n\n if (left < 0) {\n return -1;\n }\n /* over-subscribed */\n\n }\n\n if (left > 0 && (type === CODES$1 || max !== 1)) {\n return -1;\n /* incomplete set */\n }\n /* generate offsets into symbol table for each length for sorting */\n\n\n offs[1] = 0;\n\n for (len = 1; len < MAXBITS; len++) {\n offs[len + 1] = offs[len] + count[len];\n }\n /* sort symbols by length, by symbol order within each length */\n\n\n for (sym = 0; sym < codes; sym++) {\n if (lens[lens_index + sym] !== 0) {\n work[offs[lens[lens_index + sym]]++] = sym;\n }\n }\n /*\n Create and fill in decoding tables.
