WebOct 27, 2016 · 1 Answer Sorted by: 0 Let a ⋅ b = p ⋅ q + r. What's the base case for the induction? p = a, q = b, r = 0. Inductive step: a ⋅ b = p ⋅ q + r holds, then a ⋅ b = p ′ ⋅ q ′ + r ′ in the next iteration. Case 1: p is odd. If p is odd, then p ′ = p − 1 2, q ′ = 2 q, r ′ = r + q p ′ ⋅ q ′ + r ′ = … WebThe Russian Peasant's Algorithm is a recursive algorithm for multiplication that uses doubling, halving, and addition. The basic idea is that to multiply n by m, we can compute instead (n/2)* (2m) if n is even and ( (n-1)/2)* (2m) + m if n is odd. In either case the …

Depending on the size of the numbers, different algorithms are more efficient than others. Efficient multiplication algorithms have existed since the advent of the decimal system. ... This example uses peasant multiplication to multiply 11 by 3 to arrive at a result ...
WebStudents are intrigued by the algorithm as it allows one to multiply any two whole numbers knowing only the multiplication and division facts for the digit 2. Unfortunately, most textbooks do not address the natural questions which students ask about the algorithm: … WebThe code you provided is a subroutine that performs binary multiplication on two unsigned 16-bit integers (MM and NN) using the Russian peasant algorithm. It returns the product as a 16-bit unsigned integer (ANS). The subroutine first checks if MM and NN are negative by testing the sign bit (the most significant bit) of each number.
WebThis peasant's algorithm is interesting. If one must repeatedly multiply numbers by a single known multiplier such as 40, it's at least tempting to use addition and shifting rather than actual multiplication in hopes of efficiency. Doing so involves no ifs, ands (or buts..). WebThe algorithm draws on the binary system: multiplication by 2, or just adding a number two itself. Unlike, the Russian Peasant Multiplication that determines the involved powers of 2 automatically, the Egyptian algorithm has an extra step where those powers have to be found explicitly.
