# Letter space align

So I am writing an assignment for that requires me to list out a permutation of letters.

I currently have something like this

How do I make it so that each letter in the second row is directly below the letter in the first row?

Use a mono-spaced font which sets lower and upper case letters at the same width:

\documentclass{article}

\begin{document}

\noindent
{\ttfamily
a b c d e \\
E D C B A
}

\end{document}


Alternatively, arrange the letters using a tabular:

\documentclass{article}

\begin{document}

\noindent
{\ttfamily\begin{tabular}{ *{5}{c} }
a & b & c & d & e \\
E & D & C & B & A
\end{tabular}}

\end{document}


This latter approach works with non-mono-spaced fonts and you can adjust the \tabcolsep to space the letters appropriately.
