+<h2><a href="https://leetcode.com/problems/add-two-numbers/">2. Add Two Numbers</a></h2><h3>Medium</h3><hr>Add Two Numbers - You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each of their nodes contains a single digit. Add the two numbers and return the sum as a linked list.
+
+You may assume the two numbers do not contain any leading zero, except the number 0 itself.
+
+ 
+
+Example 1:
+
+[https://assets.leetcode.com/uploads/2020/10/02/addtwonumber1.jpg]
+
+
+Input: l1 = [2,4,3], l2 = [5,6,4]
+Output: [7,0,8]
+Explanation: 342 + 465 = 807.
+
+
+Example 2:
+
+
+Input: l1 = [0], l2 = [0]
+Output: [0]
+
+
+Example 3:
+
+
+Input: l1 = [9,9,9,9,9,9,9], l2 = [9,9,9,9]
+Output: [8,9,9,9,0,0,0,1]
+
+
+ 
+
+Constraints:
+
+ * The number of nodes in each linked list is in the range [1, 100].
+ * 0 <= Node.val <= 9
+ * It is guaranteed that the list represents a number that does not have leading zeros.
