Excellent! Clear and plain explanations, and it's so much cleaner when hand mark-up is by pen instead of by mouse. :) This is linked in LeetCode as "optimized solution explained" on the problem itself, but it'd be faster to take: carry = val // 10 val = val % 10 ...and make it instead: carry = 1 val = val - 10 The modulus approach is fantastic for expanding our algorithm to support adding up three or more arrays, but in our use case carry will always be 0 or 1.

@gimmeadollr

I think it's because we want the logic to be "the next thing is ___" for every iteration, so we make a dummy list node and immediately start with our logic (the next thing for the dummy node is ___). If you use dummy.val, you have the first step do the logic of "the value here is ___" and then the later steps are "the next thing is ___" which is more inconvenient to write. That's how I thought of it, not sure if that's the right way to think about it.

You could, but in my experience the dummy node generally makes building the linked list easier since you can loop through it with less conditional statements. If you don't make the dummy node, you would either have to have a separate if statement to check that our starting node is not null or find some other way to do a one-off initialization of the list. With the dummy node, you can process the nodes each time without having to worry about if it's your starting node or not.
