# [Changeling][1], 0 bytes <pre><code> </code></pre> Changeling is a language I created for [this challenge][2]. It is supposed to be hard to write Changeling programs, but this task is rather easy. Automatic reading and printing are the only forms of I/O in changeling, meaning that all Changeling programs cannot handle infinite inputs and will append a newline to the output.
