Took a 5 week crash course in summer, now I have this project due by Tuesday, and stuck. In great need. PL help me as I am lost. I got some help from others but not enough. the project is to implement a ADT using doubly link list to add, subtract, multiply, divide and square 2 big numbers. I have the add and subtract working, but need multiply and divide. PL let me know if I can be helped. Here is the code that is working for add and subtract. Need mult and divide methods.

Code:

public class Run {

public static void main(String[] args) {

LongInt l1 = new LongInt();

(integer.substring(currStart, currEnd));

Node insert = new Node(getDigits, null, curr);

insertRight(curr, insert);

curr = insert;

currStart += 4;

currEnd += 4;

}

tail = curr;

}

}
