素数和

import java.util.Scanner;
public class Main {static public boolean IsPrime(int n){if(n>1) {for(int i = 2;i<n;i++){if(n%i==0)return false;}return true;}return false;}public static void main(String args[]) {int n,m;Scanner input = new Scanner(System.in);n = input.nextInt();m = input.nextInt();int[] arr = new int[m-n+1];//输入数据int sum = 0,count = 0,i=2;while(count<m) {if(IsPrime(i))count++;if(IsPrime(i)&&count>=n){sum+=i;}++i;}System.out.println(sum);}
}

念整数

import java.util.Scanner;
public class Main {public static void main(String args[]) {String n = new Scanner(System.in).nextLine();String[] str = {"ling","yi","er","san","si","wu","liu","qi","ba","jiu"};for(int i = 0;i<n.length();i++){int index = n.charAt(i) - '0';if(i==0&&n.charAt(0)=='-')System.out.print("fu");else{if(i==0)System.out.print(str[index]);elseSystem.out.print(" "+str[index]);}}}
}

真心不喜欢java
