The answer
XOR has unique properties (like x ^ x = 0) that allow for clever, memory-efficient solutions, such as finding a missing number without using extra space.

A bitwise operator performs operations directly on the individual binary bits (1s and 0s) of integer values at the hardware level.
It shifts the binary representation of a number to the left, appending zeros. Mathematically, it is equivalent to multiplying the number by powers of 2.
Yes. Bitwise operations are processed directly by the CPU's Arithmetic Logic Unit (ALU) without complex calculations, making them incredibly fast.
