1874: Relatives欧拉函数

   欧拉函数用来计算比n小且和n互质的正整数的个数，记做：φ(n)，其中φ(1)被定义为1，但是并没有任何实质的意义。    (1)当n为质数时，显然φ(n)=n-1；    (2)当n为质数P^k时，φ(n)=p^k-p^(k-1)      证明：已知少于小于p^k的正整数个数为p^k-1个，其中和p^k不互质的正整数有{p×1,p×2,...,p×(p^(k-1)-1)}共计p^(k-1)

pku 2021 Relative Relatives(相对关系的数据结构)

  因为涉及到相对关系，我第一个想到的东西是并查集。这道题目我也差不多是用并查集的思想来做的，用数组来记录相互之间的关系，等整个关系网建立好后就来依次计算每个人的年龄。因为一个人只能有一个父亲，所以每个关系中的cname相对于所有人名的集合来讲都是unique的。我选择了每对关系中的cname作为标志，先用它排个序，然后每次用到的时候就用二分查找来寻找它对应的数组下标。这样做速度还挺快的，是0MS

I'm very miss my parent and some relatives.

          The labor holiday is only three days, for me it is hardly to go home, and as the holiday approached, I'm become more and more miss about my parent.

ACM 2021 Relative Relatives

计算Ted后代的年龄并排序第一次用结构，居然一次AC了，很爽。。运用递归查找相应节点的上一代年龄，没有则再向上查#include #include #include #include using namespace std;struct descedant {    char father[20];    char child[20];    int age;    //child的年龄    i
