判断数组中是否包含某个元素
精华
小牛编辑
178浏览
2023-03-14
在实际开发中，经常需要查询数组中的元素。例如，学校为每位同学分配了一个唯一的编号，现在有一个数组，保存了实验班所有同学的编号信息，如果有家长想知道他的孩子是否进入了实验班，只要提供孩子的编号就可以，如果编号和数组中的某个元素相等，就进入了实验班，否则就没进入。
不幸的是，C语言标准库没有提供与数组查询相关的函数，所以我们只能自己编写代码。
对无序数组的查询
所谓无序数组，就是数组元素的排列没有规律。无序数组元素查询的思路也很简单，就是用循环遍历数组中的每个元素，把要查询的值挨个比较一遍。请看下面的代码：

[有向图最小生成树-朱刘算法]
cool posted @ 2017年1月13日 10:00 in 图论 with tags 学习 , 587 阅读
做题的时候看到了这个算法，决定学习一下。
一个有向图，给定一个点，求以该点为根的最小生成树。
具体做法是这样的：先找到每个点最小的入边，如果没有环，那么这就是最小生成树。
不然就要在环中删边，并把这些环连起来。
例如点1,2形成了环，如果点3连向点，那么肯定也只能删的是（2,1）这条边。
所以可以缩点，然后缩点后的边就是原来的权值减去入点的最小入边。
递归即可。复杂度O（VE）
