Multiply Two Arbitrary-Precision Integers

Write a program that takes two arrays representing integers, and returns an integer representing their product. Solution: we can use the grade-school algorithm for multiplication which consists of multiplying the first number by each digit of the second, and then adding all the resulting terms. def multiply(num1, num2): sign = -1 if (num1[0] < 0) … Continue reading Multiply Two Arbitrary-Precision Integers
