Sorting Algorithm

This is a sorting algorithm.   It may be applied to a set of data in order to sort it.    
For comparing various sorts, see compare sorts.

Example

Given   13,

return:   [1,10,11,12,13,2,3,4,5,6,7,8,9].

import java.util.List;
import java.util.stream.*;
 
public class LexicographicalNumbers {
 
    static List<Integer> lexOrder(int n) {
        int first = 1, last = n;
        if (n < 1) {
            first = n;
            last = 1;
        }
        return IntStream.rangeClosed(first, last)
                        .mapToObj(Integer::toString)
                        .sorted()
                        .map(Integer::valueOf)
