Implement the following two methods in javascript: String multiply2(String num) - return num*2 without changing num to numeric value. You will have to scan num using a for loop. In the loop you will pull out each digit, double it, and build into another string considering carry bits. For num = “82739112345678”, return “165478224691356”. String divide2(String num) - return num/2(integer division) without changing num to numeric value. You will have to scan num using a for loop. In the loop you will pull out one or two digits, halve it, and build into another string considering borrow bits. For num = “165478224691357”, return “82739112345678”.
