My issue
Why it shows run time error
My code
import java.util.*;
import java.lang.*;
import java.io.*;
class Codechef
{
public static void main(String[] args) throws java.lang.Exception
{
// your code goes here
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
int arr[] = new int[10];
for (int i = 0; i < n; i++)
{
arr[i] = sc.nextInt();
}
int prefix[] = new int[10];
prefix[0]=arr[0];
for (int i = 1; i < n; i++)
{
prefix[i]=prefix[i-1]+arr[i];
}
int t = sc.nextInt();
for (int i = 0; i < t; i++)
{
int count = 0;
int a = sc.nextInt();
int b = sc.nextInt();
System.out.println(prefix[b-1]-prefix[a-1]+arr[a-1]);
}
}
}
