The following table shows what is stored in a subset of a computer's memory:

Address Byte

$000000000$

$...$

a$-411110000$

a$-301011010$

a$-210111100$

a$-100000001$

a $10000000$

a$+110110100$

a$+211111111$

a$+300011000$

a$+400111100$

$...$

Assuming the computer uses big endian byte order, what $32-$bit binary value is stored at address a$+3?$ Separate each nibble in your answer with a space. If the value cannot be determined from the above table, answer "unknown".
