      // Sample
      var a = 2.3;
      var a1 = a > 2 ? true : false;
      var a2 = a > 2 ? "true" : "false";
      // c# if shorthand without else
      var a3 = a < 2 ? "true" : null;
      var a4 = a < 2 ? "true" : default(string);
      // Its application
      double[] arr = new double[] { 1.2, 2.3, 3.5, 1.5, 1.6, 2.4, 1.8 };
      var max1 = arr.Select(v => v > 2 ? 1 : -1).ToArray();
      var max2 = arr.Select(v => v > 2 ? 1 : -1).ToArray().Where(u => u > 0).ToArray();
      var max3 = arr.Select((v, i) => v > 2 ? i : -1).ToArray().Where(u => u > 0).ToArray();
      var max4 = arr.Select((v, i) => v == arr.Max() ? i : -1).ToArray().Where(u => u > 0).ToArray();
