Binary extended euclidean algorithm

WebJul 4, 2024 · Introduction: Stein’s algorithm or binary GCD algorithm helps us compute the greatest common divisor of two non-negative integers by replacing division with arithmetic shifts, comparisons, and subtraction. It provides greater efficiency by using bitwise shift operators. This algorithm can be implemented in both recursive and iterative ways.
