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:

(Integer/toBinaryString 25) ; returns "11001"
(Integer/toOctalString 25)  ; returns "31"
(Integer/toHexString 25)    ; returns "19"

(dotimes [i 20]
  (println (Integer/toHexString i)))
