Removing the borders from algorithm listings

Question

I am relatively new to LaTeX. If I use standard algorithm and algorithmic environment for my algorithm listings I'm getting the borders displayed around the table with the pseudocode. How to remove them? I also want to have the caption of the algorithm below the pseudocode - it is currently above. I believe the problem is extremely easy but googling didn't give me any hints for that.

If you are using the algorithm package, it is enough to use the plain option:

\documentclass{article}
\usepackage{algorithmic}
\usepackage[plain]{algorithm}

\begin{document}

\begin{algorithm}
\begin{algorithmic}
  \STATE $sum\gets 0$
  \STATE $i\gets 1$
  \WHILE{$i\le n$}
  \STATE $sum\gets sum+i$
  \STATE $i\gets i+1$
  \ENDWHILE
\end{algorithmic}
\caption{Calculate $y = x^n$}
\label{alg:test}
\end{algorithm}

\end{document}
