  • Have a look at any of these: https://tex.stackexchange.com/questions/288362/doubly-linked-list-tikz https://tex.stackexchange.com/questions/86766/array-of-linked-lists-like-in-data-structure https://tex.stackexchange.com/questions/394432/how-to-draw-circular-linked-list https://tex.stackexchange.com/questions/296022/drawing-a-linked-list-as-a-tree Those are about linked lists but the concept for drawing those is the same. – Henri Menke May 02 '18 at 06:18

Do you need TikZ for this ?

\documentclass[varwidth,border=7pt]{standalone}
\begin{document}
    $\fbox{x}\rightarrow\fbox{x}\fbox{x}\fbox{x}\fbox{x}$
\end{document}

  • This solution breaks as soon as you have a list of characters with different depth and height. For example, the following will look jagged: $\fbox{x}\rightarrow\fbox{x}\fbox{q}\fbox{t}$ – Janez Kuhar Jun 04 '21 at 09:08
  • @JanezKuhar Not very hard to adapt, using \strut or \vphantom, like in $\fbox{x\strut}\rightarrow\fbox{x\strut}\fbox{q\strut}\fbox{t\strut}$. – Kpym Jun 05 '21 at 10:11
