title: spoj TESTINT time limit exceed
body: <p>The code basically adds two numbers. I was wondering if we can optimise it even more and reduce the execution duration. The online judge for <a href="http://www.spoj.com/problems/TESTINT/" rel="nofollow noreferrer">the SPOJ TESTINT problem</a> tells me "time limit exceeded".</p>
  
  <p>Here's my code:</p>
  
  <pre><code>#include &lt;cstdio&gt;
  int main() 
  {
      int a, b;
      scanf("%d\n%d", &amp;a, &amp;b);
      printf("%d", a + b);
      return 0;
  }
  </code></pre>
