title: Find the minimum of a number sequence with negative numbers with Linq
body: <p>The following code doesn't give the expected minimum -1. Instead I get 0.
  Do you know why?</p>
  
  <pre><code>class MainClass
  {
      public static void Main (string[] args)
      {
          string numbers = "-1 0 1 2 3 4 5";
          Console.WriteLine (numbers.Split (' ')[0]);     // output: -1
          string max = numbers.Split(' ').Max();
          string min = numbers.Split(' ').Min();
          Console.WriteLine("{0} {1}", max, min);         // output: "5 0"
      }
  }
  </code></pre>
