I have to flip all bits in a binary representation of an integer. Given:
The output should be
What is the bitwise operator to accomplish this when used with an integer? For example, if I were writing a method like
int flipBits(int n);, what would go in the body? I need to flip only what’s already present in the number, not all 32 bits in the integer.
~ unary operator is bitwise negation. If you need fewer bits than what fits in an
int then you’ll need to mask it with
& after the fact.
