Given a root node reference of a BST and a key, delete the node with the given key in the BST. Return the root node reference (possibly updated) of the BST. Basically, the deletion can be divided into two stages: Search for a node to remove. If the n…

二叉树变量只是一个地址 public static void main(String[] args) { TreeNode t = new TreeNode(3); help(t); System.out.println(t.val); } public static void help(TreeNode t) { t.val = 6; } 上边代码通过地址改变了二叉树,输出为6,但是下边代码却只是传入函数的二叉树变量指向了另一个地址,外界的二叉树变量和二叉树的值没有变,输出还是3 public…
