Java :: Triangle Problem
<p>We have triangle made of blocks. The topmost row has 1 block, the next row down has 2 blocks, the next row has 3 blocks, and so on. Compute the total number of blocks in such a triangle with the given number of rows. </p>

<pre><code> triangle(0) =&gt; 0     
 triangle(1) =&gt; 1     
 triangle(2) =&gt; 3     
</code></pre>

<p>The function signature is      <code>public int triangle(int rows) { }</code></p>

<p>I'm unable to proceed with this problem and struggling to solve it.     </p>
