Modulo operation using bit shift
Web27 jun. 2016 · You are expected to use this trick, like the modulo reduction, after hashing. You can hash to the [0, 2^32) range. But at some point, I doubt you’ll beat a modulo operation. You need to hash your objects in all cases. You should never “just” use the modulo reduction. What you typically do is hash and then reduce. WebUsing bitwise shift-with-carry or rotate-with-carry operations If you don't have any OR or AND operations, but you do have a shift-to-right-with-carry or a rotate-to-right-with-carry, you can implement addition using those. Requirements: Rotation-to-right with carry

Let positive integer m be a base and function f ( x, m) is defined over positive integers x, m such that. f ( x, m) = x, if x < m. f ( x, m) = f ( ⌊ x / m ⌋ + x % m, m), if x ≥ m. Without ⌊ x / m ⌋, the function f is the same as the Traditional Modulo Operation. This function is interesting and may have some ...

Web8 apr. 2024 · This is a simplification of the modulo operation using bit operation. In Java HashMap, the length of the table is always a power of two ( 2^x ), it means that modulo operation by a bitwise AND ( & ). This can be done because n is always a power of two, thus n - 1 is always a bit pattern having 1 at each position.
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.
