c++ map question
<p>If I have a map like this:</p>

<pre><code>std::map&lt;char, std::vector&lt;char&gt; &gt; m;
m['A'].push_back('a');
m['A'].push_back('b');
m['A'].push_back('c');
m['B'].push_back('h');
m['B'].push_back('f');
</code></pre>

<p>How would I find and delete 'b'? Is this possible?</p>
