How to convert a String to lowercase using lambda expressions
<p>I want to know how to convert a string to lowercase using the <code>ToLower</code> function <code>(Char -&gt; Char)</code>.</p>

<p>This is the code I have so far:</p>

<pre><code>let newlist = (\(h:t) -&gt; c (h) ++ newlist (\c -&gt; toLower c)
</code></pre>

<p>I can't see how to do it without using recursion, which I don't know how to use in a lambda expression</p>
