Getting Runtime error(NZEC) on submitting Java program

Hello, I am new to this platform. I’ve failed to submit two solutions. I get a runtime error on “Little Chef and Sums” question - the first question in the practice section. There must be something I’m missing. Please point it out. Thanks

I’m submitting this code:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class MainClass {
public static void main(String[] args){
    try{
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String firstLine = br.readLine();
        int testCasesCount = Integer.parseInt(firstLine);
        for(int i = 0; i < testCasesCount; i++){
            int arrayLength = Integer.parseInt(br.readLine());
            String arrayStr = br.readLine();
            String[] arrayStrArr = arrayStr.split(" ");
            int[] arr = new int[arrayLength];
            for(int j = 0; j < arrayLength; j++){
                arr[j] = Integer.parseInt(arrayStrArr[j]);
            }

            int min = arr[0];
            for(int j = 0; j < arrayLength; j++){
                if(min > suffixSum(j, arr) + prefixSum(j, arr)){
                    min = suffixSum(j, arr) + prefixSum(j, arr);
                }
            }
            System.out.println(min+1);
        }
    } catch(IOException e){
        e.printStackTrace();
    }
}

private static Integer suffixSum(int beginPos,int[] arr){
    int sum = 0;
    for(int i = beginPos; i < arr.length; i++){
        sum += arr[i];
    }
    return sum;
}

private static Integer prefixSum(int beginPos, int[] arr){
    int sum = 0;
    for(int i = 0; i < beginPos; i++){
        sum += arr[i];
    }
    return sum;
}
}

I also couldn’t submit this solution(although it is another question but in both the cases I’m getting correct answers but answers do not seem to submit) - https://discuss.codechef.com/questions/111590/getting-wrong-answer-on-codechef-but-getting-right-output-on-my-computer-free-ticket-problem

Do solutions after competition time count as wrong answers? :frowning:

No, solutions after competitions doesn’t count as Wrong answers, you can check out my solution my solution

If you have any questions, please ask

as far as I can see you are computing the min(pre sum+suff sum) rather then their min indexes . correct this approach first.
