Problem 5. Min, Max, Sum and Average of N Numbers

// Problem 5. Min, Max, Sum and Average of N Numbers
//
// 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.
//
//   Examples:
// n    output
// 3    min = 1
// 2    max = 5
// 5    sum = 8
// 1    avg = 2.66

let input = ['3',
    '2',
    '5',
    '1'
