title: Write a function that returns the square of a number without using *,+ or pow
body: <p>The task is to write a function that takes n as an input where n is a number (from -32768 to 32768) and returns the square of that number. Simple task except for the fact that we cannot use any operators such as *,+ or even use any Math. functions such as pow. eval is not allowed as well. 
  Even more challenging is that we must keep the character code count <strong>less than 39 characters</strong>.</p>
  
  <p>I absolutely cannot think of a way to get the square of a number without using the + or *. And even worse, to keep the character count less, it's impossible for me.</p>
  
  <p>Codes like this won't work because: I used the plus sign and the character count is more than 60. </p>
  
  <pre><code>function sq(n){
     var res=n;
     for(i=1;i&lt;n;i++)
     res+=n;
  return res;
  }
  </code></pre>
  
  <p>If n is a decimal, we are expected to return the nearest whole number as the result.
  Thank you for reading all of this!</p>
  
  <p>Edit: My problem has been solved. Thank you to everyone who has tried to help me with their codes as it helped me gain a new aspect of solving each problems. 
  Thank you very much again!</p>
