解题思路：

全部插入到叶子节点即可

class Solution {public TreeNode insertIntoBST(TreeNode root, int val) {if (root == null) {TreeNode node = new TreeNode(val);return node;}if (root.val < val) {root.right = insertIntoBST(root.right, val);}if (root.val > val) {root.left = insertIntoBST(root.left, val);}return root;}
}
