如何在 Latex 中编写伪代码算法？

Question

我想在 Latex 中编写伪代码算法，如附图所示。我已经编写了代码来实现与上述算法相同的效果，但它对我来说不起作用。这个代码正确吗？

\IncMargin{1em}
 \begin{algorithm}
\SetKwInOut{Part 1}{input}
\SetKwInOut{Part 2}{output}
\Part 1{}
\BlankLine
\emph{abcdefgh $D$ ijklmnop}\;
\emph{ abcdefgh $A$}\;
\For{$k\leftarrow 1$ \KwTo $M$}{
            \For {each $m$ $ ∈ $ {1, 2, …, J}{
                \emph{ abcdefgh $D$}\;
                \emph{abcdef }\;
}
\Part 2{}
\emph{abcdefgh $A$ ijklmnop}\;
\emph{ abcdefgh $A$}\;
\For {each $m$ $ ∈ $ {1, 2, …, J}{
\emph{ abcdefgh $D$}\;
\emph{abcdef }\;
\emph{abcdef }\;
}
}
\For{$k\leftarrow 1$ \KwTo $M$}{
\emph{ abcdefghklmop}\;
\emph{ abcdefghklmop}\;
\emph{ abcdefghklmop}\;
}
\caption { Algorithm Sample}

以下更符合常规语法algorithm2e：

\documentclass{article}

\usepackage{amsmath}
\usepackage[ruled,vlined]{algorithm2e}
\DontPrintSemicolon
\newcommand{\To}{\mbox{\upshape\bfseries to}}

\begin{document}

\begin{algorithm}
  \caption{Algorithm sample}
  \textbf{Part 1}\;
  \nl abcdefgh $\{ D_i \}_{i = 1}^M$ ijklmnop\;
  \nl abcdefgh $A_m$\;
  \nl \For{$K = 1$ \To{} $M$}{%
    \ForEach{$m \in \{1, 2, \dots, J\}$}{
      abcdefgh $\{ D \}_m^t$\;
      abcdefgh\;
    }
    \textbf{Part 2}\;
    abcdefgh $\{ G_i \}_{i = 1}^K$\;
    abcdefgh $D_m$\;
    \ForEach{$m \in \{1, 2, \dots, J\}$}{
      abcdefgh $\{ G \}_m^y$\;
      abcdefgh\;
      abcdefgh\;
    }
  }
  \nl \For{$K = 1$ \To{} $M$}{
    abcdefghijklmno\;
    abcdefghijklmno\;
    abcdefghijklmno\;
  }
\end{algorithm}

\end{document}
