Question

java 为什么会出现Exception in thread "main" java.util.NoSuchElementExceptio......

import java.util.Scanner;
public class Main
{
@SuppressWarnings("resource")
public static void main(String[]args)
{
Scanner scan = new Scanner(System.in);
int T = scan.nextInt();
int l[] =new int[T+1];
for(int k=1;k<=T;k++)
{
Scanner scan1 = new Scanner(System.in);
l[k]=scan1.nextInt();
}
for(int k=1;k<=T;k++)
{
for(int i=1;i<=l[k];i++)
{
if(l[k]==((i+1)*i)/2)
{
System.out.println(i);
break;
}
if(i==l[k])
System.out.println("No Solution");
}
}
}
}

在本地可以运行,但提交到网上,就会出现
Exception in thread "main" java.util.NoSuchElementException
at java.util.Scanner.throwFor(Scanner.java:838)
at java.util.Scanner.next(Scanner.java:1461)
at java.util.Scanner.nextInt(Scanner.java:2091)
at java.util.Scanner.nextInt(Scanner.java:2050)
at Main.main(Main.java:13)

提交到哪里 ？ 是不是System.in 哪里有问题呢？
