WebMay 16, 2024 · Binary GCD should generally be better than naive Euclid, but a being very small compared to b is a special circumstance that may trigger poor performance from Binary GCD. I’d try one round of Euclid, i.e., gcd (b, a%b) where gcd is Binary GCD. (But without knowing the underlying problem here, I’m not sure that this is the best advice.) … WebNov 19, 2011 · This Wikipedia entry has a very dissatisfying implication: the Binary GCD algorithm was at one time as much as 60% more efficient than the standard Euclid Algorithm, but as late as 1998 Knuth concluded that there was only a 15% gain in efficiency on his contemporary computers.

WebMay 9, 2024 · Intuitively I'd ignore Stein's algorithm (on that page as "Binary GCD algorithm") for Python because it relies on low level tricks like bit shifts that Python really doesn't excel at. Euclid's algorithm is probably fine. In terms of your implementation of the Euclidean algorithm You don't need to manually check which of a and b is greater. WebSep 15, 2024 · Given two Binary strings, S1 and S2, the task is to generate a new Binary strings (of least length possible) which can be stated as one or more occurrences of S1 as well as S2.If it is not possible to generate such a string, return -1 in output.

WebFor the proof of correctness, we need to show that gcd ( a, b) = gcd ( b, a mod b) for all a ≥ 0, b > 0. We will show that the value on the left side of the equation divides the value on the right side and vice versa. Obviously, this would mean that the left and right sides are equal, which will prove Euclid’s algorithm. Let d = gcd ( a, b).
