Latex; How to remove the algorithm number in algorithm captions?

How one can remove the algorithm number in the algorithm caption?
Solution: just add \renewcommand{\thealgorithm}{} after \begin {algorithm}

How one can remove the line number in the algorithm body?
Solution:
Define a new command:
\def\NoNumber#1{{\def\alglinenumber##1{}\State #1}\addtocounter{ALG@line}{-1}}
and put the text in \NoNumber{}

Sample Latex Code
\documentclass[11pt]{article}
\usepackage{algorithmicx}
\usepackage{algorithm}
\usepackage{algpseudocode}
\def\NoNumber#1{{\def\alglinenumber##1{}\State #1}\addtocounter{ALG@line}{-1}}
\begin{document}
\begin{algorithm}
\renewcommand{\thealgorithm}{}
\caption{Test Algorithm}\label{euclid}
\begin{algorithmic}[1]
\Procedure{Euclid}{$a,b$}\Comment{The g.c.d. of a and b}
\State $r\gets a\bmod b$
\While{$r\not=0$}\Comment{We have the answer if r is 0}
\State $a\gets b$
\State $b\gets r$
\State $r\gets a\bmod b$
\EndWhile\label{euclidendwhile}
\State \textbf{return} $b$\Comment{The gcd is b}
\NoNumber{This line will not have a number!}
\EndProcedure
\end{algorithmic}
\end{algorithm}
\end{document}
