### A good answer might be:

    FEED      1111 1110 1110 1101
    BECA      1011 1110 1100 1010
    ----      ---- ---- ---- ----
    BEC8      1011 1110 1100 1000

# XOR Instruction

XOR Operation on Bits
first operand | 0 | 0 | 1 | 1
second operand | 0 | 1 | 0 | 1
| __ | __ | __ | __
result | 0 | 1 | 1 | 0

You will not be surprised to find that there is a XOR instruction:

    xor  d,s,t        # $d <-- bitwise XOR between $s with $t.

Recall that the result of XOR is one when only one operand bit is one.

### QUESTION 9:

What is the bitwise XOR of the following?

    FEED
    BECA
