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
andnum2
is < 110. - Both
num1
andnum2
contain only digits0-9
. - Both
num
