本文介绍了一种通过预先计算并存储所有可能结果的方法来解决一类特定数论问题的编程思路。这种方法首先通过一个判断素数的函数确定输入是否为素数，接着使用另一个函数计算特定条件下整数n的平方除以7的余数的幂次表达式的最终结果。通过这种方式，可以在实际运行时快速查找答案，避免了复杂的实时计算。

思想：暴力打表，意思就是用最简单的思想花费较长的时间先把题目出现的所有情况的数据结果存下来，然后写程序的时候把所有可能的情况存在一个数组中，直接访问数组输出。

# include <stdio.h>
# include <math.h>
# include <iostream>
# define MAXN 10000+10
using namespace std;
bool judge(int n)
{
    if(n==0||n==1)
        return false;
    for(int i=2; i<=sqrt(n); i++)
    {
        if(n%i==0)
            return false;
    }
    return true;
}
int zhao(int n)
{
    double a=n*n/7.0;
    int t=(int)a;
    int ans=1;
    for(int i=1; i<=t; i++)
    {
        ans=(ans%7)*(n%7)%7;
    }
    return ans;
}
int main()
{
//  FILE *fp=fopen("D://data.txt","w");
//    for(int i=1;i<=10000;i++)

例如让你算n的n次方的值的个位数上的数（有点绕口），就是比如n是4，就是4*4*4*4=256,256的个位数上是6，所以6就是所求的值。 （其实这个例子是有算法的，但假如你不知道这个算法）你可以采用找规律的方式。你可以先让n在50以内所有的值都通过暴力打表先打印出来，然后找到规律 （你会发现每20个数字会有规律产生~） #include <bits/stdc++.h> using namespace std; typedef long long ll; int a[21] = {-1,

基于PSO算法优化支持向量机参数的MATLAB仿真源码：SVM与PSO-SVM性能对比
12-22
本研究聚焦于运用MATLAB平台，将支持向量机（SVM）应用于数据预测任务，并引入粒子群优化（PSO）算法对模型的关键参数进行自动调优。该研究属于机器学习领域的典型实践，其核心在于利用SVM构建分类模型，同时借助PSO的全局搜索能力，高效确定SVM的最优超参数配置，从而显著增强模型的整体预测效能。 支持向量机作为一种经典的监督学习方法，其基本原理是通过在高维特征空间中构造一个具有最大间隔的决策边界，以实现对样本数据的分类或回归分析。该算法擅长处理小规模样本集、非线性关系以及高维度特征识别问题，其有效性源于通过核函数将原始数据映射至更高维的空间，使得原本复杂的分类问题变得线性可分。 粒子群优化算法是一种模拟鸟群社会行为的群体智能优化技术。在该算法框架下，每个潜在解被视作一个“粒子”，粒子群在解空间中协同搜索，通过不断迭代更新自身速度与位置，并参考个体历史最优解和群体全局最优解的信息，逐步逼近问题的最优解。在本应用中，PSO被专门用于搜寻SVM中影响模型性能的两个关键参数——正则化参数C与核函数参数γ的最优组合。 项目所提供的实现代码涵盖了从数据加载、预处理（如标准化处理）、基础SVM模型构建到PSO优化流程的完整步骤。优化过程会针对不同的核函数（例如线性核、多项式核及径向基函数核等）进行参数寻优，并系统评估优化前后模型性能的差异。性能对比通常基于准确率、精确率、召回率及F1分数等多项分类指标展开，从而定量验证PSO算法在提升SVM模型分类能力方面的实际效果。 本研究通过一个具体的MATLAB实现案例，旨在演示如何将全局优化算法与机器学习模型相结合，以解决模型参数选择这一关键问题。通过此实践，研究者不仅能够深入理解SVM的工作原理，还能掌握利用智能优化技术提升模型泛化性能的有效方法，这对于机器学习在实际问题中的应用具有重要的参考价值。 资源来源于网络分享，仅用于学习交流使用，请勿用于商业，如有侵权请联系我删除！

sdut数据结构pta链表

### 山东理工大学 SDUT 数据结构 PTA 平台链表练习题资源 #### 关于线性表的操作实践 在山东理工大学的数据结构课程中，通过PTA平台进行的线性表操作实践旨在帮助学生掌握线性表的基础理论及其应用技巧。具体来说，在实验过程中会涉及到对顺序表的理解以及如何保持其有序性的插入操作[^1]。 对于给定的一个已经按照递增顺序排列好的顺序表`L`，如果要将新元素`X`加入其中而不破坏原有的升序关系，则需要遍历整个列表找到合适的位置完成插入动作。这不仅考察了学员们对于基本概念如逻辑结构、物理表示法等方面的知识水平；同时也锻炼到了编程能力——特别是针对数组这种静态分配内存空间所构建出来的线性表实施有效算法设计的能力。 #### 创建逆序链表实例分析 另一个值得注意的例子是在处理动态链接存储方式下的线性集合时遇到的任务：创建一个以相反次序保存输入序列的新单向连接串行组。此过程由名为`createlist`的过程负责执行，它持续接收来自标准输入流中的正值直到遇见终止符(-1)，随后依据接收到数值反向组建起始端点指向最终添加项的一系列节点组成的链条[^2]。 ```c typedef struct Node { int data; struct Node *next; } ListNode; ListNode* createlist() { int value; ListNode *head = NULL, *current = NULL; while(scanf("%d", &value), value != -1){ ListNode *newNode = (ListNode *)malloc(sizeof(ListNode)); newNode->data = value; newNode->next = head; head = newNode; } return head; } ``` 这段C语言代码展示了怎样实现上述功能，每次读取一个新的整数就将其作为新的头部来更新现有的链表，从而自然形成了原始输入序列反转后的效果。 #### 单向链表状态变化模拟 考虑到更复杂的场景，比如在一个原本存在的简单无环路路径上执行入队与出队两种不同类型的修改行为之后观察整体形态的变化情况。假设最开始有一个仅含三个成员{1 -> 2 -> 3}的小型队伍，当有第四个参与者4请求加入并且被安排到最后面形成扩展版图景{1 -> 2 -> 3 -> 4}; 接着首位队员离开后留下来的布局变成了{2 -> 3 -> 4}[^3]。 这些例子充分体现了通过对实际问题建模并借助计算机程序求解的方式加深理解和记忆重要知识点的有效方法论价值所在。
