* Cleaning up public/ and documenting js/css libs. This commit mostly addresses #1484 by moving vendor'ed plugins into a vendor/ directory and documenting their upstream source and license in vendor/librejs.html. This also proves gitea is using only open source js/css libraries which helps toward reaching #1524. * Removing unused css file. The version of this file in use is located at: vendor/plugins/highlight/github.css * Cleaned up librejs.html and added javascript header A SafeJS function was added to templates/helper.go to allow keeping comments inside of javascript. A javascript comment was added in the header of templates/base/head.tmpl to mark all non-inline source as free. The librejs.html file was updated to meet the current librejs spec. I have now verified that the librejs plugin detects most of the scripts included in gitea and suspect the non-free detections are the result of a bug in the plugin. I believe this commit is enough to meet the C0.0 requirement of #1534. * Updating SafeJS function per lint suggestion * Added VERSIONS file, per request

\frametitle{Size Lemma for Balanced Trees}
|

\begin{itemize}
|

\item
|
|
\begin{assertion}[id=size-lemma,type=lemma]
|
|
Let $G=\tup{V,E}$ be a \termref[cd=binary-trees]{balanced binary tree}
|
|
of \termref[cd=graph-depth,name=vertex-depth]{depth}$n>i$, then the set
|
|
$\defeq{\livar{V}i}{\setst{\inset{v}{V}}{\gdepth{v} = i}}$ of
|
|
\termref[cd=graphs-intro,name=node]{nodes} at
|
|
\termref[cd=graph-depth,name=vertex-depth]{depth} $i$ has
|
|
\termref[cd=cardinality,name=cardinality]{cardinality} $\power2i$.
|
|
\end{assertion}
|
|
\item
|
|
\begin{sproof}[id=size-lemma-pf,proofend=,for=size-lemma]{via induction over the depth $i$.}
|
|
\begin{spfcases}{We have to consider two cases}
|
|
\begin{spfcase}{$i=0$}
|
|
\begin{spfstep}[display=flow]
|
|
then $\livar{V}i=\set{\livar{v}r}$, where $\livar{v}r$ is the root, so
|
|
$\eq{\card{\livar{V}0},\card{\set{\livar{v}r}},1,\power20}$.
|
|
\end{spfstep}
|
|
\end{spfcase}
|
|
\begin{spfcase}{$i>0$}
|
|
\begin{spfstep}[display=flow]
|
|
then $\livar{V}{i-1}$ contains $\power2{i-1}$ vertexes
|
|
\begin{justification}[method=byIH](IH)\end{justification}
|
|
\end{spfstep}
|
|
\begin{spfstep}
|
|
By the \begin{justification}[method=byDef]definition of a binary
|
|
tree\end{justification}, each $\inset{v}{\livar{V}{i-1}}$ is a leaf or has
|
|
two children that are at depth $i$.
|
|
\end{spfstep}
|
|
\begin{spfstep}
|
|
As $G$ is \termref[cd=balanced-binary-trees,name=balanced-binary-tree]{balanced} and $\gdepth{G}=n>i$, $\livar{V}{i-1}$ cannot contain
|
|
leaves.
|
|
\end{spfstep}
|
|
\begin{spfstep}[type=conclusion]
|
|
Thus $\eq{\card{\livar{V}i},{\atimes[cdot]{2,\card{\livar{V}{i-1}}}},{\atimes[cdot]{2,\power2{i-1}}},\power2i}$.
|
|
\end{spfstep}
|
|
\end{spfcase}
|
|
\end{spfcases}
|
|
\end{sproof}
|
|
\item
|
|
\begin{assertion}[id=fbbt,type=corollary]
|
|
A fully balanced tree of depth $d$ has $\power2{d+1}-1$ nodes.
|
|
\end{assertion}
|
|
\item
|
|
\begin{sproof}[for=fbbt,id=fbbt-pf]{}
|
|
\begin{spfstep}
|
|
Let $\defeq{G}{\tup{V,E}}$ be a fully balanced tree
|
|
\end{spfstep}
|
|
\begin{spfstep}
|
|
Then $\card{V}=\Sumfromto{i}1d{\power2i}= \power2{d+1}-1$.
|
|
\end{spfstep}
|
|
\end{sproof}

\begin{note}
|
|
\begin{omtext}[type=conclusion,for=binary-tree]
|
|
This shows that balanced binary trees grow in breadth very quickly, a consequence of
|
|
this is that they are very shallow (and this compute very fast), which is the essence of
|
|
the next result.
