		int[] scores = new int[scan.nextInt()];
		char[] grades = new char[scores.length];


		System.out.print("Enter " + scores.length + " scores: ");
		for (int i = 0; i < scores.length; i++) {
			scores[i] = scan.nextInt();
		}
		scan.close();


		getGrades(scores, grades);


		for (int i = 0; i < scores.length; i++) {
			System.out.println("Student " + i + " score is " + scores[i] + " and grade is " + grades[i]);
		}
	}


	public static int max(int[] array) {
		int max = array[0];
		for (int i = 1; i < array.length; i++) {
			if (array[i] > max)
				max = array[i];
		}
		return max;
	}


	public static void getGrades(int[] scores, char[] grades) {
		int best = max(scores);
		for (int i = 0; i < scores.length; i++) {
			if (scores[i] >= best - 10)
				grades[i] = 'A';
			else if (scores[i] >= best - 20)
				grades[i] = 'B';
			else if (scores[i] >= best - 30)
				grades[i] = 'C';
			else if (scores[i] >= best - 40)
				grades[i] = 'D';
			else
				grades[i] = 'F';
