Problem Statement

Programming languages often have built-in routines to convert a non-negative integer for printing in different number bases. Such common number bases might include binary, Octal and Hexadecimal.

Print a small range of integers in some different bases, as supported by standard routines of your programming language.

This is distinct from Number base conversion as a user-defined conversion function is not asked for.) The reverse operation is Common number base parsing.

Let's start with the solution:

range(0, 33).each { |n|
    printf(" %6b %3o %2d %2X\n", ([n]*4)...);
}
