题意:根据这个式子来递推求得每个随机数x,step和mod给定,seed(0)=0.如果推出来的序列是mod个不重复的数字(0~mod-1)则打印good,否则bad(因为不能产生所有的数). 思路: 用一个数组记录所产生过的数,当出现数字已记录过时,判断是否个数为mod个.若是就返回good. #include <bits/stdc++.h> #define LL long long using namespace std; ; bool ans[N]; int main() { //fre…
Uniform Generator  Computer simulations often require random numbers. One way to generate pseudo-random numbers is via a function of the form where ``  " is the modulus operator. Such a function will generate pseudo-random numbers (seed) between 0 an…
UVa 1583 题目大意:如果x加上x的各个数字之和得到y,那么称x是y的生成元. 给定数字n,求它的最小生成元 解题思路:可以利用打表的方法,提前计算出以i为生成元的数,设为d,并保存在a[d]中(a[d]=i),反复枚举,若是初次遇到或遇到更小的则更新 相关说明:本来按书上来,在更新数组a时,if里是有或上 i < a[y]这个条件的, 但观察到由于i是从小到大枚举的,因此只会更新一次,即第一次填进去的就是最小生成元,因此去掉仍然AC /* UVa 1583 Digit Generator…
