Because the unsigned right shift operator ">>>" shifts a ZERO into the leftmost position.

In binary 16 is 10000, now shift the bits two places to the right. We get 100. Then add a 0 into the leftmost position, we get 0100 which is 4.
(2)

In binary 16 is 10000, now shift the bits three places to the right (>>>2)and we get 10 which is 2

So how the 2 and 4 is correct?
