You are given two non-empty linked lists representing two non-negative integers. The most significant digit comes first and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. You may assume the two numbers do not contain any lead...
First, you want to return(total) on the same line as your For loop. Otherwise, your function sends this value before it ever loops a second time. Second, just focus on adding the currentnumvalue to total. Before you can do this you must set total = 0 before the For loop starts. I...
