I don't know how easy or hard this is, but I am so confused and cannot think of it.

I have two arrays in reverse order.

So basically

Array a[]=321 ( ie the number is 123)

Array b[] = 9001 (i.e the number is 1009)

So I have to make a add method which accepts these two arrays as arguments.

Then I add those two numbers and return the value in string or an array, doesn't matter.

How do I do add and subtract method for this problem. As I have to make sure about the carry digit as if we add 9 and 3 its 12, so 1 is carry or so.

I hope you guys/gals understand my problem and if you have any questions then please let me know

Thanks in advance
