title: how to implement a method be the driver a private recursive routine
body: <p>I am in the second part of my homework, where it asked us to: Implement reverse by having reverse be the driver for a private recursive routine. reverse will create a StringBuffer and pass it to the recursive routine.</p>
  
  <p>Can someone explain what the question is exactly asking. </p>
  
  <p>I have written the reverse method (first-part of my HW) as follow and it is right. </p>
  
  <pre><code>public static void reverse(int input) {
          if (input &lt;= 0) {
              //System.out.print(" Enter positive input");
          } else {
              System.out.print(input % 10);
              reverse(input / 10);
          }
  </code></pre>
  
  <p>However, for the second part I did the following but I dont even understand the question properly and what it wants me to do. Can someone help me or gave me an example?</p>
  
  <pre><code>private void reverse(int input){
  
          }
  </code></pre>
