Hope this helps

    Scanner scanner = new Scanner(System.in);
            int size = scanner.nextInt();
            int[] input = new int[size]; 

            for (int i = 0; i < size; i++){
        input[i] = scanner.nextInt();
    }

    int count = 0;
    for (int i = 0; i < size; i++){

        int sum = 0;
        for (int j = i; j < size; j++){

            sum += input[j];
            if (sum < 0) count++; 
        }
    }
    System.out.println(count);
