python tk编程出现: Tcl_AsyncDelete: async handler deleted by the wrong thread
问题现象 我有一个主TK界面, 同时又创建了一个新的独立的TK窗口. 这个新的TK窗口设置为topmost, 用于超时提醒的. 这个窗口虽然是topmost的, 但是可能没有输入焦点. 我想设置一个快捷键, 用于关闭此窗口. 也就是说, 在另外的线程中关闭tk窗口. 采用的方法是在另外线程中调用ro ......
[题解] CF29D Ant on the Tree
CF29D Ant on the Tree 题目知识点：LCA。 题目传送门 题意 给定一棵以 \(1\) 为节点的树，再给定树的所有叶子节点的一个序列。 现在执行一个操作：从 \(1\) 开始遍历每个节点，并返回根，要求每条边经过的次数一定为 \(2\) 。 问是否能够使得访问节点序列中叶子节点的 ......
