title: How to insert bit into long number
body: <p><p>There is a sequence of bits. Is it possible to insert the bit in particular position between others bits?
  <p>For example:</p>
  
  <ol>
  <li>We have some number <code>long n</code>, which looks in binary like <code>10010</code>;</li>
  <li>We have some method <code>long insert(long numb, position)</code>;</li>
  <li>After using <code>insert(n, 2)</code> we must get following sequence of bits:10<strong>1</strong>010 </li>
  </ol>
  
  <p>Thank you for answering! </p>
