Web2 dagen geleden · For getting n modulus d, we just need to return 0 to i -1 (from right) bits of n as they are and other bits as 0. For example if n = 6 (00..110) and d = 4 (00..100). Last set bit in d is at position 3 (from right side). So we need to return last two bits of n as they are and other bits as 0, i.e., 00..010. Now doing it is so easy, guess it…. WebThe right shift operator shifts the bits towards the right. This means it does the exact opposite of the left shift operator i.e. every time we shift a number towards the right by 1 bit it divides that number by 2. Eg. 96 >> 1 = 48 Now since we have got enough idea about the shift operators let's use them to divide a number with another number.
