大家好，又见面了，我是你们的朋友全栈君。public class test {
public static void main(String[] args) {
System.out.println(“Hello World!”);
ListNode a = new ListNode(0);
ListNode b = new ListNode(0);
a.val = 2;
a.next=new ListNode(4);
a.next.next=new ListNode(5);
b.val=5;
b.next=new ListNode(6);
b.next.next=new ListNode(4);
ListNode c = addTwoNumbers(a,b);
}
public static ListNode addTwoNumbers(ListNode a, ListNode b) {
ListNode cListNode = new ListNode(0) ;
ListNode c = cListNode,al=a,bl=b;//c存的是地址 c是指向cListNode的指针
int ext = 0;
while(al!=null||bl!=null){
int va = (al!=null)?al.val:0;
int vb = (bl!=null)?bl.val:0;
int flag= va+vb+ext;
ext =flag/10;
c.next = new ListNode(flag%10);
c = c.next;
if(al!=null) al=al.next;
if(bl!=null) bl=bl.next;
}
if(ext>0){
c.next = new ListNode(ext);
}
return cListNode.next;
}
}
