title: Perform IEnumerable method
body: <p>Simplying the problem statement to List of int, lets say I have this</p>
  
  <pre><code> List&lt;int&gt; range = new List&lt;int&gt;(10) { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };
  </code></pre>
  
  <p>User inputs 24, I would need a Early feed value as 20 and late feed value as 30<br>
  User inputs 99, I would need a Early feed value as 90 and late feed value as 100<br>
  <strong>User inputs 20, I would need a Early feed value as 20 and late feed value as 20</strong>  </p>
  
  <p>Is there a Lamba Expression or linq statement to get this sort of result.</p>
  
  <p>My real input is not List of int, I have just simlified it, more keen on the lamba or linq expression to get the result</p>
