WebMar 21, 2024 · The Bitwise Algorithms is used to perform operations at the bit-level or to manipulate bits in different ways. The bitwise operations are found to be much faster and are sometimes used to improve the efficiency of a program. For example: To check if a number is even or odd. This can be easily done by using Bitwise-AND (&) operator. WebA bit wise XOR (exclusive or) operates on the bit level and uses the following Boolean truth table: Notice that with an XOR operation true OR true = false where as with operations …
