Are bitwise operations faster than arithmetic ones?
Yes. Bitwise operations are processed directly by the CPU's Arithmetic Logic Unit (ALU) without complex calculations, making them incredibly fast.

A bitwise operator performs operations directly on the individual binary bits (1s and 0s) of integer values at the hardware level.
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.
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.
