public class App {


	public static void main(String[] args) {


		Scanner keyBoard = new Scanner(System.in);
		System.out.print("Enter numbers of marks: ");
		int n = keyBoard.nextInt();
		int highest = Integer.MIN_VALUE;
		int lowest = Integer.MAX_VALUE;
		double sum = 0;
		int average = 0;
		System.out.print("Enter 10 marks: ");
		// a, b, and c should be accomplished using only one loop
		for (int i = 0; i < n; i++) {
			int mark = keyBoard.nextInt();
			sum += mark;
			// a) Find and display the highest mark
			if (mark > highest) {
				highest = mark;
			}
			// b) Find and display the lowest mark
			if (mark < lowest) {
				lowest = mark;
			}
		}
		// c) Compute and display the average mark
		average = (int) sum / n;
		System.out.println("Highest Mark = " + highest + "%");
		System.out.println("Lowest Mark = " + lowest + "%");
		System.out.println("Average = " + average + "%");
		keyBoard.close();
