I have a table of contents as follows:
\documentclass{report}
\begin{document}
\tableofcontents
\clearpage
\chapter{TEST}
\section{Introduction}
\section{Test section one}
\subsection{Test subsection}
\subsection{Test subsection}
\subsubsection{Test subsubsection}
\subsection{Test subsection}
\end{document}
I want to appear statement "Chapter 1: TEST" instead of "1 TEST" in the list of contents. Can you help?
