-1 is the following number in binary:
1111 1111 1111 1111 1111 1111 1111 1111
Shift to the right by one bit to get:
0111 1111 1111 1111 1111 1111 1111 1111 -> a 1 falls off the end here.
The zero on the left appears because we are using the >>> operator (compare with what the >> operator does)
What's the decimal equivalent of the result?

Getting someone to think and try something out is much more useful than just telling them the answer.
