under the online to find the reasons, found that it is no use to import the jar package (it’s strange that I have is in accordance with the project with the idea to create a spring, why am I still missing bag), and then find is the lack of aspectjweaver – 1.9.4. Jar the jar package, in the following website to download the jar package:

https://mvnrepository.com/ download, to import the jar package, and compile: find and mistake

It turns out that when SpringBoot automatically loads configuration files via AutoConfigure, it is necessary to ensure that the resource folder under SRC folder is a resource folder. As shown in , the resource folder will have several small horizontal bar marks in the lower right corner, while the normal folder is not. Right-click on Make Dictionary as and change the normal folder to the resource folder, and the project will start normally.

The sum of the two numbers of leetcode title: gives two non-empty linked lists to represent two non-negative integers. Their individual bits are stored in reverse order, and each of their nodes can only store one digit. if we add these two Numbers together, a new linked list will be returned to represent their sum. you can assume that neither number begins with 0, except for the number 0. example: method: simulate class Solution { public ListNode addTwoNumbers(ListNode l1, ListNode l2) { ListNode head = null, tail = null; int carry = 0; while (l1 != null || l2 != null) { int n1 = l1 != null ? l1.val : 0; int n2 = l2 != null ? l2.val : 0; int sum = n1 + n2 + carry; if (head == null) { head = tail = new ListNode(sum % 10); } else { tail.next = new ListNode(sum % 10); tail = tail.next; } carry = sum / 10; if (l1 != null) { l1 = l1.next; } if (l2 != null) { l2 = l2.next; } } if (carry > 0) { tail.next = new ListNode(carry); } return head; } } complexity analysis time complexity: O(Max (m,n)), where m,n is the length of two linked lists. We’re going to go through all the places in both lists, and it only takes order (1) time to process each place. space complexity: O(\ Max (m,n)). The length of the answer list is at most the length of the longer list +1. This entry was posted in How to Fix and tagged Algorithm question on 2020-10-14 by Robins.
