#include <stdio.h>
#include <math.h>

int main()
{
    int n;
    scanf("%d", &n);
    double score;
    int i, min = 100, max = 0;
    double avg;
    double sum = 0;
    for (i=1; i<=n; i++)
    {
        scanf("%lf", &score);
        if (score > max)
        {
            max = ceil(score);
        }
        if (score < min)
        {
            min = ceil(score);
        }
        sum += score;
    }
    avg = sum / n;
    printf("%d %d\n", min, max);
    printf("%.2f", avg);
    return 0;
}
