In this tutorial, we are going to solve a leetcode problem Add Two Numbers in Python.
Given two non-negative integers num1 and num2 represented as strings, return the product of num1 and num2, also represented as a string.
Note: You must not use any built-in BigInteger library or convert the inputs to integer directly.
Input: num1 = "2", num2 = "3"
Output: "6"
Input: num1 = "123", num2 = "456"
Output: "56088"
class Solution:
def multiply(self, num1: str, num2: str) -> str:
return str(int(num1)*int(num2))
step1: As we are solving this problem in python so we'll be going to use some advantages of using python i.e. built-in functions
step2: we simply write the return statement and inside it we use the typecasting which will convert the integer multiplication into a string.
