title: Arrange in increasing order of their Big Oh Complexity
body: <p>So if given   </p>
  
  <p>4n^2, log3(n), 20n, n^2.5, log(n!), n^n, 3^n, n log (n), 100n^(2/3), 2^n, 2^(n+1), n!, (n-1)!, 2^2n </p>
  
  <p>The order (increasing order of their big O complexity) would be   </p>
  
  <p>log3(n) &lt; 20n &lt; n logn &lt; 4n^2 &lt; 100n^(2/3) &lt; log(n!) &lt; n^(2.5) &lt; 2^n &lt; 2^(n+1) &lt; 3^n &lt; 2^(2n) &lt; (n-1)! &lt; n^n &lt; n! </p>
  
  <p>this is when n is a large number. Is that right?</p>
