**This challenge continues from 476 - Sum, it is recommended that you finish that one first, and modify your code based on it to start this challenge.**

Implement a type `Multiply<A, B>`

that multiplies two non-negative integers and returns their product as a string. Numbers can be specified as string, number, or bigint.

For example,

`type T0 = Multiply<2, 3> // '6' type T1 = Multiply<3, '5'> // '15' type T2 = Multiply<'4', 10> // '40' type T3 = Multiply<0, 16> // '0' type T4 = Multiply<'13', '21'> // '273' type T5 = Multiply<'43423', 321543n> // '13962361689'`
