代码随想录算法训练营第四天 | LeetCode 24. 两两交换链表中的节点、19.删除链表的倒数第N个节点、面试题 02.07. 链表相交、142.环形链表II

1. LeetCode 24. 两两交换链表中的节点1.1 思路定义虚拟头节点dummyhead，要不然每次针对头结点（没有前一个指针指向头结点），还要单独处理，并且cur=dummyhead，因为这里的步骤是首先cur下一个先指向节点2，然后节点2下一个指向节点1，再然后是节点1下一个指向节点3，最后让cur指向翻转后的节点1，直接cur=first就行。所以需要dummyhead的原因就是因....

写在前面，bad day。一定要坚持住，真的要坚持住，养成习惯就好了。今天很乱，也被各种事情搞得心烦。庆幸的是我今天没赖床，所有的题目都刷过了一遍，本来今天打算复盘一下昨天以前的题的。10点后就被迫去做一些无法推掉的社交，无法继续专心学习，节假日比工作还忙。我的作息是晚上10点睡4点起，因为下班后没精力学习算法。只好在上班之前把重要的事情先做完。24. 两两交换链表中的节点讲解链接https:/....

代码随想录算法训练营第四天| 24. 两两交换链表中的节点 19.删除链表的倒数第N个节点 (面试题) 02.07. 链表相交 142.环形链表II

·今日学习的文章链接和视频链接代码随想录（programmercarl.com）·自己看到题目的第一想法（24. 两两交换链表中的节点）画图看起来挺简单的，但实现的时候很绕。（19.删除链表的倒数第N个节点）倒叙转为正序，遍历删除节点。（02.07. 链表相交）陷入链表相交的概念之中，题中给出的是一种规则，以此为标准即可。（142.环形链表II ）题目没看懂。 ·看完代码随想录之后....
