Hints

1. Shift back the bits

There are two operators for shifting to the right, but only one will always insert a 0.

2. Set some bits

One of the bit wise operators will always set a bit to 1 where the bits in both values are 1.

3. Flip specific bits

There is an bit operation that will flip a bit where the mask is 1.

4. Clear specific bits

One of the bit operations clears bits where the bit in the mask is 0.
But you may need to combine it with another operator to clear bits where the mask is 1.
