Binary gcd algorithm
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. Please note that the resultant string must not have incomplete strings S1 or S2. For example, “1111” can … WebFeb 18, 2015 · But can go further if we use the Binary GCD algorithm.
