Given two non-negative integers num1 and num2 represented as
strings, return the product of num1 and num2, also represented as
a string.
Example 1:
Input: num1 = "2", num2 = "3"
Output: "6"
Example 2:
Input: num1 = "123", num2 = "456"
Output: "56088"
Note:
- The length of both
num1 and num2 is < 110.
- Both
num1 and num2 contain only digits 0-9.
- Both
num1 and num2 do not contain any leading zero,
except the number 0 itself.
- You must not use any built-in BigInteger library or convert the
inputs to integer directly.
