问题: Given two binary trees, write a function to check if they are equal or not. Two binary trees are considered equal if they are structurally identical and the nodes have the same value. 分析: 考虑使用深度优先遍历的方法,同时遍历两棵树,遇到不等的就返回. 代码如下: /** * Definition f…

将树序列化为字符串,空节点用符号表示,这样可以唯一的表示一棵树. 用list记录所有子树的序列化,和目标树比较. List<String> list = new ArrayList<>(); public boolean isSubtree(TreeNode s, TreeNode t) { helper(s); helper(t); String tt = list.get(list.size()-1); for (int i = 0;i<list.size()-1;i++…
