【算法刷题】—7.24一题带你脑筋急转弯，灯泡开关

✨今日算法一题灯泡开关文章目录✨今日算法一题灯泡开关题目描述思路详解代码与结果在这里插入图片描述✨总结灯泡开关题目描述思路详解本题首先一看并没有头绪，那么我们列出来几个看一下。这里借用一个图解，左边表示第几轮，O表示亮，X表示暗。我们寻找一下规律。>这里我们以第六个灯泡为例，我们发现，影响第六...

跟着姚桑学算法-费解的开关

基本算法题. 费解的开关你玩过“拉灯”游戏吗？25 盏灯排成一个 5×5 的方形。每一个灯都有一个开关，游戏者可以改变它的状态。每一步，游戏者可以改变某一个灯的状态。游戏者改变一个灯的状态会产生连锁反应：和这个灯上下左右相邻的灯也要相应地改变其状态。我们用数字 1 表示一盏开着的灯，用数字 0 表示...

PG一般查询了一次后，第二次查询会快很多，按我的理解应该是生成了执行计划缓存，这个执行计划缓存能显式清除或禁用吗我这边想测试不同算法的执行效率，有没有不重启服务类似SET SQL_NO_CACHE=ON;这种会话级别的开关
