1546번: 평균

 

BufferedReader와 StringTokenizer 개념을 활용하면 꽤나 쉬운 문제였다

 

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

public class Main {

	public static void main(String[] args) throws NumberFormatException, IOException {

		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

		int num = Integer.parseInt(br.readLine());

		StringTokenizer st = new StringTokenizer(br.readLine(), " ");

		int max = -9999;
		double sum = 0.0;

		for(int i=0 ; i<num; i++) {
			int score = Integer.parseInt(st.nextToken());
			if(score > max) max = score;
			sum += score;
		}

		System.out.println( (sum/max) * 100 / num);
	}
}
