我一次又一次得到NZEC(非零退出代码)错误,因为这个代码在我的电脑上运行得非常好。请帮忙。我认为问题在于使用BufferedReader类的输入代码。我的代码是: -
import java.io.*;
class Prime1
{
public static void main(String args[])throws Exception
{
int count=0;
System.out.println("Enter the number of test cases");
BufferedReader br= new BufferedReader(new InputStreamReader(System.in));
int T=Integer.parseInt(br.readLine());
for(int i=1;i<=T;i++)
{
System.out.println("Enter the value of m and n such that 1<=m<=n<=1000000000");
BufferedReader br1= new BufferedReader(new InputStreamReader(System.in));
int m=Integer.parseInt(br1.readLine());
BufferedReader br2= new BufferedReader(new InputStreamReader(System.in));
int n=Integer.parseInt(br2.readLine());
for(int j=m;j<=n;j++)
{
for(int k=1;k<=j;k++)
{
if(j%k==0)
count++;
}
if(count==2)
System.out.println(j);
count=0;
}
System.out.println();
}
}
}
答案 0 :(得分:2)
不要打印这样的语句:
System.out.println("Enter the number of test cases");
自动检查解决方案,任何额外输出都将被视为错误答案。
您的程序不适用于以空格分隔的输入。尝试使用Scanner
来读取输入。例如:
Scanner in = new Scanner(System.in);
int T = in.nextInt();
for (int i = 1; i <= T; i++) {
int m = in.nextInt();
int n = in.nextInt();
