The input is a byte stream. The required output is a list or array of integers decoded from it.

The highest two bits in first byte of each integer value in the input stream decide how long the value is:

  1. If the highest bit of the first byte is 0;

    then the output is the numeric value of the other 7-bits in that byte. 

    01010101 == 85

  2. If the highest bit is 1; and the second highest bit is 0;

    The output is the numeric value of lowest 14-bits of the first and second bytes treated as a big-endian short. 

    10101010_10101010 == 10922

  3. If the highest two bits of the first byte are 1;

    Then the output is the numeric value of the lowest 22-bits of the first three bytes of input (big-endian). 

    11001100_11001100_11001100 == 838860

Thoughts?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
