Basically I generated 250 random numbers each for a series of sizes between 5 and 2990 bits # NOTE: For naive_multiply and karatsuba_multiply, you may # only use the Python "*" operator on single digit multiplications # and on multiplying numbers by powers of 10. ndsvw / Karatsuba-binary-multiplying-Python. As a res Pythons are carnivores and in the wild they can eat animals such as antelope, monkeys, rodents, lizards, birds and caimans. Run the code to see the time complexity comparison for normal Binary Multiplication and Karatsuba Algorithm. I don’t think that 1.
