To flip all the bits of a bit pattern, we need a bitwise operator that can toggle (invert) each bit position. The XOR operator (^) does exactly that, it compares each bit of the two operands and sets the corresponding result bit to 1 if the operands have different bit values. So, if we XOR a bit pattern with a mask of all 1s, we effectively flip all its bits.
