WebAug 2, 2024 · The bitwise exclusive OR operator ( ^) compares each bit of its first operand to the corresponding bit of its second operand. If the bit in one of the operands is 0 and the bit in the other operand is 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0.
WebDec 13, 2024 · Bit Rotation: A rotation (or circular shift) is an operation similar to shift except that the bits that fall off at one end are put back to the other end.
