Introduction

If you are getting an erroneous output when running a program, it can be a frustrating experience. It can be difficult to determine the cause of the problem and even more difficult to find a solution. This article will provide an overview of the most common causes of erroneous output and provide tips on how to troubleshoot and resolve the issue. We will also discuss some of the best practices for avoiding erroneous output in the future. By understanding the causes of erroneous output and following the best practices outlined in this article, you can ensure that your programs run smoothly and produce the desired results.

Solution

The most likely cause of an erroneous output is a coding error. This could be due to a typo, incorrect syntax, or incorrect logic. To identify and fix the issue, it is important to review the code and look for any errors. Additionally, it may be helpful to use debugging tools such as a debugger or a code analyzer to identify the source of the error.


If i understand the problem correctly it should take first int then scan the n lines and creating sort of 2 dimension list/array or so then should accept int of questions about what is in position (x,y) in this 2 dimensional object covering what is out of bounds as an “ERROR!”.

import java.util.ArrayList;
import java.util.Scanner;

public class Solution {

    public static void main(String[] args) {
    /*
     * Enter your code here. Read input from STDIN. Print output to STDOUT.
     * Your class should be named Solution.
     */
    Scanner sc = new Scanner(System.in);
    int n = sc.nextInt();
    sc.nextLine();
    ArrayList array[] = new ArrayList[n];
    for (int i = 0; i < n; i++) {
        ArrayList list = new ArrayList();
        Scanner linSc = new Scanner(sc.nextLine());
        while (linSc.hasNextInt()) {
            list.add(linSc.nextInt());
        }
        linSc.close();
        array[i] = list;
    }
    n = sc.nextInt();
    for (int i = 0; i < n; i++) {
        int k = sc.nextInt();
        int l = sc.nextInt();
            try {
                System.out.println(array[k - 1].get(l));
            } catch (IndexOutOfBoundsException e) {
                System.out.println("ERROR!");
            }
        }
        sc.close();
    }
}

If you are getting an erroneous output, it is likely due to a coding error. This could be caused by a typo, incorrect syntax, or a bug in the code. To troubleshoot the issue, you should first review the code to identify any potential errors. If you are unable to find the source of the problem, you may need to debug the code to determine the exact cause. Debugging involves running the code step-by-step to identify where the error is occurring. Once you have identified the source of the error, you can then make the necessary changes to fix the issue.
