{ "data": { "question": { "questionId": "43", "questionFrontendId": "43", "boundTopicId": null, "title": "Multiply Strings", "titleSlug": "multiply-strings", "content": "

Given two non-negative integers num1 and num2 represented as strings, return the product of num1 and num2, also represented as a string.

\n\n

Note: You must not use any built-in BigInteger library or convert the inputs to integer directly.

\n\n

 

\n

Example 1:

\n
Input: num1 = \"2\", num2 = \"3\"\nOutput: \"6\"\n

Example 2:

\n
Input: num1 = \"123\", num2 = \"456\"\nOutput: \"56088\"\n
