# 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? |
