Algorithms

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

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

&nbsp;
Example 1:
<pre>Input: num1 = "2", num2 = "3"
Output: "6"
</pre>Example 2:
<pre>Input: num1 = "123", num2 = "456"
Output: "56088"
</pre>
&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= num1.length, num2.length &lt;= 200</code></li>
	<li><code>num1</code> and <code>num2</code> consist of digits only.</li>
	<li>Both <code>num1</code> and <code>num2</code>&nbsp;do not contain any leading zero, except the number <code>0</code> itself.</li>
</ul>
