题目链接思路：就是运用二分查找。每查找一步比较一下分支的走向。如果两个节点的分支走向不同，那么现在这个节点就是最低的公共祖先，如果相同，那么接下来的查找还可能相同，程序要继续运行。/***Definitionforabinarytreenode.*publicclassTreeNode{*intval;*TreeNodeleft;*TreeNoderight;*TreeNode(intx){val

1.问题描述给定一棵二叉树和两个节点p、q，查找这两个节点最近的公共父节点。2.方法与思路由于给定的是一颗普通的二叉树，与之前的二叉搜索树不一样，子树之间没有大小关系。但是可以用另一种思路，当前节点如果是p，q的公共最先节点，则p，q一定在当前节点的左右子树中。可以用递归解决。/***Definitionforabinarytreenode.*structTreeNode{*intval;*Tre

1.问题描述给定一棵二叉搜索树（BST），查找两个节点的最短公共祖先节点。2.方法与思路这是一个简化的LCA问题，由于是二叉搜索树，树的本身就有一定节点，左儿子节点的值小于父节点值，父节点值小于右儿子节点的值。这样我们可以递归查找就可以了，如果当前节点值大于给定两个节点的值就去它的左子树查找，如果当前节点的值小于给定两个节点的值，就去它的右子树查找，否则返回该节点。/***Definitionfo
