Hints

Some (not all) of the tests assume the value is Int32, so please avoid forcing it to be anything else.

1. Shift back the bits

• This is a right-shift.
• Note the instruction that the results should be left-filled with zeros.

2. Set some bits

• Bits are set by bitwise OR with a mask. This is extremely common.

3. Flip specific bits

• There is an old joke among programmers that cryptographers discovered XOR and forgot to read the rest of the manual.

4. Clear specific bits

• Simple AND logic will do the opposite of what you need.
• How do you flip all the bits in the mask?
