点击打开题目链接本想梳理一下中国剩余定理的相关知识，但是由于今天集训了一天，脑子cpu已经烧掉了，所以找到一个比较简单的贪心的题目。题目大意为：一条直线上有n个点，要求标记其中某些点使得对于直线上的每个点，在距离R内至少有一个被标记的点。求出标记最少的次数。求局部最优解的问题，从第一个点开始，标记的点一定在它的右边或者是它自己，然后以标记点为起点，标记最右边一个可以满足

点击打开题目链接本弱猪想借这个题梳理一下并查集的用法。并查集是用来判断两个元素是否为同一集合的数据结构。也就是说，并查集只能合并，无法分割。并查集通过树形结构实现（不是二叉树奥），通过判断每个元素的根节点是否相同来判断两个元素是否为相同集合。回到这个题上，题目中有x,y,z三类，是“判断是否属于同一类的问题”，显然考察并查集的相关知识，只不过这个题目除了判断是否同类，还增加了捕食关

今天翻看了一下以前写的博客，从最开始第一次集训去年的4月1号开始写，到现在已经过去一年多时间，以前写的博客，现在看来虽然题目很水(虽然现在也很水=.=)，但却是看到一个新的知识点就饶有兴趣地写出来的。而现在却缺了当时的那点魄力。大二已经结束了，大三下学期就要复习考研了，还有上学期一学期的时间，时间已经不那么充裕，还有好多知识点没有学到，但这条路是正确的。脚踏实地，学下去,。初心不改。题目...
