3,103,659 | 3,103,660 | Calculate closest matches from array value combinations | <p>I have an array of part lengths, for examples sake:-</p>
<pre><code>array(150, 180, 270);
</code></pre>
<p>I then have a measurement <code>($a = 440)</code></p>
<p>I need to calculate the two <strong>closest</strong> possible combinations of lengths which are greater than <code>$a</code> without manually having to write hundreds of possible combinations in order to work it out.</p>
<p>So:</p>
<p><code>150</code><br>
<code>180</code><br>
<code>270</code> </p>
<p><code>150 + 150</code><br>
<code>150 + 180</code><br>

<p><code>180 + 180</code><br>
<code>180 + 270</code></p>

<p><code>150 + 150 + 150</code><br>
<code>150 + 150 + 180</code></p>
<p>..and so on.</p>
<p>This will need to run for a set number of times, rather than just finding the first two matches and stopping, as <code>150 + 150 + 150</code> would be a <strong>closer</strong> match to <code>$a</code> than <code>270 + 270</code> but may run after.</p>
<p>edit: I also need to store the combination of parts which made up the match, preferably in an array.</p>
<p>I hope I've explained this well enough for somebody to understand.</p>

I want to so whichever link you click, it moves all the divs that are being shown, down to make room for the newest one.</p>

4,357,732 | 4,357,733 | Creating a struct and a class with the same name | <p><strong>Summary</strong>: What happens if you declare a <code>struct</code> and a <code>class</code> with the same name.</p>
<p><strong>Details</strong>:</p>
<p>I'm reviewing some code and I saw a warning like this:</p>
<pre><code>warning: struct 'foo' was previously declared as a class
</code></pre>
<p>When compiling with clang there were also a couple of places where clang added notes saying:</p>
<pre><code>foo.h:29:1: note: did you mean struct here?
class foo;
^~~~~
struct
</code></pre>
<p>Obviously this is not a good coding practice to have a struct and a class with the same name. It looks like what happened is the developer was writing his own class and used a name that was already in use in another file that he was including and he did not notice that.</p>
<p>However, my question is will the compiler be able to tell the difference between the variables that were declared as <code>class foo</code> and the ones that were <code>struct foo</code>?</p>
<p><strong>Edit</strong>:</p>
<p>Actually what was happening was that the developer was using the <code>class foo</code> in a <code>class bar</code> that he had created. I think that in the meantime the place where the <code>class foo</code> was declared had been changed to a <code>struct bar</code>. So that was why the code was compiling. So I guess the answer to my question is that <code>struct</code> and <code>class</code> are interchangeable when declaring objects. Still I guess it's a good idea to use them consistently.</p>

<p>I have 2 questions regarding a ListView in Android:</p>
<ol>
<li><p>How can I <strong>get</strong> the color of the listview's focused row ?
I tried to use the <strong>ListView.getSelector()</strong> method, which according to its documentation should give me what I'm looking for, but it's giving me a Drawable object which I don't know how to retrieve the color from (if possible...).</p></li>
<li><p>How can I <strong>set</strong> the color of the listview's focused row ?
Here I tried to use the <strong>setSelector()</strong> method on the listview, passing it a ColorDrawable object, but the result of doing it is that the whole background of the list view is painted in that color... and this is not what I wanted of course...</p></li>
