LeetCode Multiply Strings

Multiply Strings

Given two numbers represented as strings, return multiplication of the numbers as a string.

Note: The numbers can be arbitrarily large and are non-negative.

import java.math.BigInteger;
public class Solution {
    public String multiply(String num1, String num2) {
        BigInteger n1 = new BigInteger(num1);
        BigInteger n2 = new BigInteger(num2);
     
        return n1.multiply(n2).toString();
    }
}
