Ex: 1 XOR 0 = 1, 1 XOR 1 = 0. The xor operator will retain the bit if the bit is xored with 0. Ex: 0 XOR 0 = 0, 0 XOR 1 = 1. Assigned newBits with the opposite values of oldBits if flipBits is true. Ex: If oldBits = [1, 1, 0, 1] and flipBits is 1, then newBits = [0, 0, 1, 0] Web21 Aug 2024 · Alternatively, the XOR operator ( ^) can also invert a boolean. Before considering the implementation, let's quickly understand how the XOR operator works. Given two boolean variables b1 and b2, b1 ^ b2 is true only if b1 and b2 have different values, for example: true ^ true = false false ^ false = false true ^ false = true middle eastern hair salon near me
