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. WebShifting all of a number's bits to the left by 1 bit is equivalent to multiplying the number by 2. Thus, all of a number's bits to the left by n bits is equivalent to multiplying that number by 2 n. Notice that we fill in the spots that open up with 0s. If a bit goes further left than the place of the most-significant digit, the bit is lost.
