Just do Right Shift 8 times. Thats it.
But Normally we say that & with 0xFF00 and do right shift 8 times. Please remember to think before answering what is the question and the possibilities to reduce instructions/ execution time/ memory consumptioin.
Simple Example, If we want to multiply a value by 2, we put
"value * 2"
But efficient way would be
"Value << 1"
That is left shift one time will give multiples of two. This will reduce the CPU cycles consumed.
Left Shift is faster than Multiplication
