如何删除 algorithm2e 中的多余空间

Question

我正在使用algorithm2e包来编写算法。我需要定义描述为多行的函数。仅在第一个函数中，algorithm2e在第二行、第三行等行中添加额外空格。但是从第二个函数开始，它并没有添加我想要的额外空间。我需要删除第一个函数行中添加的额外空间（第一行之后的所有行）。脚本在这里。我使用 ACM 会议模板，我需要将算法分为两列，因为它很长（不像这个小样本）。

脚本如下：

\documentclass[sigconf]{acmart}
\pagestyle{empty}
\usepackage{amsmath}
\usepackage[ruled,vlined]{algorithm2e} 
\usepackage{multicol} 

\begin{document}
\title{Title Here}

\begin{abstract}
Abstract here.
\end{abstract}

\maketitle

\section{Algorithm}
\begin{algorithm*}
\begin{multicols}{2}
    \SetKwInOut{Input}{input}\SetKwInOut{Output}{output}\SetKwInOut{Functions}{Functions}
    \SetKwFunction{Query}{Query}\SetKwFunction{Calc}{Calc}


    \Functions
    {
        \Query{$a,b$}: Queries a and b and returns the answer as c. This function name is Query.\;
        \Calc{$a,b$}: Calculates a and b and returns the answer as c. This function name is Calc.\;
    }


\caption{The algorithm}
\label{alg:query-verify}
\end{multicols}
\end{algorithm*}

\end{document}

如下图所示：

此解决方案改编自https://tex.stackexchange.com/a/335862/90297：

基本上更新 \SetKWInOut 命令以便缩进大小为 0em。

\documentclass[sigconf]{acmart}
\pagestyle{empty}
\usepackage{amsmath}
\usepackage[ruled,vlined]{algorithm2e} 
\usepackage{multicol} 

\makeatletter
\renewcommand{\SetKwInOut}[2]{%
  \sbox\algocf@inoutbox{\KwSty{#2\algocf@typo:}}%
  \expandafter\ifx\csname InOutSizeDefined\endcsname\relax% if first time used
    \newcommand\InOutSizeDefined{}\setlength{\inoutsize}{\wd\algocf@inoutbox}%
    \sbox\algocf@inoutbox{\parbox[t]{\inoutsize}{\KwSty{#2\algocf@typo\hfill:}}~}\setlength{\inoutindent}{0em}%{\wd\algocf@inoutbox}% <------------
  \else% else keep the larger dimension
    \ifdim\wd\algocf@inoutbox>\inoutsize%
    \setlength{\inoutsize}{\wd\algocf@inoutbox}%
    \sbox\algocf@inoutbox{\parbox[t]{\inoutsize}{\KwSty{#2\algocf@typo\hfill:}}~}\setlength{\inoutindent}{0em}%{\wd\algocf@inoutbox}% <------------------
    \fi%
  \fi% the dimension of the box is now defined.
  \algocf@newcommand{#1}[1]{%
    \ifthenelse{\boolean{algocf@hanginginout}}{\relax}{\algocf@seteveryparhanging{\relax}}%

    {\let\\\algocf@newinout\hangindent=\inoutindent\hangafter=1\parbox[t]{\inoutsize}{\KwSty{#2\algocf@typo\hfill:}}~##1\par}
    \algocf@linesnumbered% reset the numbering of the lines
    \ifthenelse{\boolean{algocf@hanginginout}}{\relax}{\algocf@reseteveryparhanging}%
  }}%
