How can one create a tree structure in LaTeX that begins with a single number and extends with an arbitrary number of arrows that connect numbers below with numbers above such that the head faces upward? For example, a tree of this form:
I see that there are similar trees without directed arrows as shown here. Similarly, I see that there are trees with directed arrows that are not similar as shown here. Is there a way to combine these two elements in tikz?
Is simply copying the following elements from \usepackage{tikz,forest}
sufficient or are entirely different elements needed?
\documentclass{article}
\usepackage{tikz,forest}
\begin{document}
\texttt{grow} used in a Ti\textit{k}Z tree
\begin{tikzpicture}
\node{1}
child{node{child 1}}
child[grow=south]{node{child 2}
child child child
}
;
\end{tikzpicture}
end{forest}
end{document}
