[백준] 1546번: 평균 - java

https://www.acmicpc.net/problem/1546

 

 

간단하게 평균과 최댓값을 구하는 문제

 

import java.util.Scanner;

public class App {
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        int N = sc.nextInt();
        int A[] = new int[N];
        for(int i=0; i<N; i++){
            A[i] = sc.nextInt();
        }
        int max = 0;
        int sum = 0;
        for(int j=0; j<N; j++){
            if(max<A[j]) max = A[j];
            sum += A[j];
        }
        System.out.println(sum*100.0/max/N);
    }
}
