            //Write a program that reads from the console a sequence of n integer numbers and returns the minimal, the maximal number,                  the sum and the average of all numbers(displayed with 2 digits after the decimal point).The input starts by the number n (alone in a line) followed by n lines, each holding an integer number. The output is like in the examples below.

            //3     min = 1
            //2     max = 5
            //5     sum = 8
            //1     avg = 2.67

            double average = 0;
            int count = 0;

                int n1 = int.Parse(Console.ReadLine());
                sum += n1;
                average = sum / number;
            }

            Console.WriteLine();

            Console.WriteLine("min={0}", minimal);
            Console.WriteLine("max={0}", maximal);
            Console.WriteLine("sum={0}", sum);
            Console.WriteLine("avg={0:F2}", average);
        }
    }
