算法：Java计算二叉树从根节点到叶子结点的最大路径和

要求从根节点到叶子结点的最大路径和，可以通过递归遍历二叉树来实现。对于二叉树中的每个节点，我们都可以考虑包含该节点的最大路径和。在递归的过程中，我们需要不断更新全局最大路径和。 ...

算法宝典1——Java版本（此系列持续更新，这篇文章有20道）（有题目的跳转链接）（此份宝典包含了链表、栈、队列、二叉树的算法题）（下）

【扩展问题】为什么快指针每次走两步，慢指针走一步可以？假设链表带环，两个指针最后都会进入环，快指针先进环，慢指针后进环。当慢指针刚进环时，可能就和快指针相遇了，最差情况下两个指针之间的距离刚好就是环的长度。此时，两个指针每移动一次，之间的距离就缩小一步，不会...
