algorithm - 如何解决背面编辑器中缺少 $ 插入的错误

Question

我正在尝试使用 algorithm2e 包在背面在线编辑器中编写算法。我不断收到错误，不确定导致此错误的原因是什么，这是我的代码：

\documentclass{article}
\usepackage{xcolor}
\usepackage[linesnumbered,ruled,vlined]{algorithm2e}

\title{Algorithm template updated}
\author{Roy}

\newcommand\mycommfont[1]{\footnotesize\ttfamily\textcolor{blue}{#1}} \SetCommentSty{mycommfont}

\SetKwInput{KwInput}{Input}                % Set the Input
\SetKwInput{KwOutput}{Output}              % set the Output


\begin{document}
\maketitle

\begin{algorithm}[H]
\DontPrintSemicolon

\KwInput{C}
\KwOutput{groups in C}
initialization $D_b^C \leftarrow 0$\;
\For{$Each node v \in c   $}
{
   $Nd_c (v)$ neighbors of v within distance \delta$(i)$\;
   \For{$Each node w$ \in $Nd_c (v)   $}
   {
      \if{$dist(v, w)$ \leq \delta$(i)$}
      {
         $d ̅$ \leftarrow$ (d_v+ d_w)\div$\;
         \if{ $d ̅ \geq Nd_$c  }
         {
            $Nd_c \leftarrow d ̅$\;
         }
      }
   }
    \if{$d_v$ \leq $Nd_c$}
    {
       label v as detected\;
    }
}
\caption{**Groups in Data**}
\end{algorithm}
\end{document}
