WebNov 14, 2024 · The bitwise XOR (exclusive or) performs an exclusive disjunction, which is equivalent to adding two bits and discarding the carry. The result is zero only when we have two zeroes or two ones. XOR can be used to toggle the bits between 1 and 0. Thus when used in a loop toggles its values between 1 and 0. i = i ^ 1. 例如: WebThe bitwise NOT, or bitwise complement, is a unary operation that performs logical negation on each bit, forming the ones' complement of the given binary value. Bits that are 0 become 1, and those that are 1 become 0. For example: NOT 0111 (decimal 7) = 1000 (decimal 8) NOT 10101011 (decimal 171) = 01010100 (decimal 84) The result is equal to … WebApr 7, 2024 · There are 41 two-digit numbers where bitwise AND results in 0. All the two-digit numbers will lie in the range [10,99] both inclusive and for each of them, check if the AND of the adjacent digits is equal to 0. Like, say for 10, there are 2 digits, 1 and 0; if we do 1&0, this returns 0, so 10 is a valid number. chry cirrus
