Suppose that memory contains the following data starting at the 
address given in the left column (in hex dump format):
<pre>
0x00001000: 0000 0000 0000 0000 fffe 1020 0102 feff
</pre>
On a little-endian architecture machine, 
what is the numerical value of the two-byte unsigned integer starting at address 0x00001008?
Write your answer as an expression involving sums of powers of 256.
~+ 255 * 256^0 + 254 * 256^1
