How to change indentation of specific comment in algorithmic environment?

I have the following code:

documentclass{article}  

usepackage{algorithm}
usepackage{algorithmic}

newcounter{ALC@tempcntr}% Temporary counter for storage
newcommand{LCOMMENT}[1]{%
    setcounter{ALC@tempcntr}{arabic{ALC@rem}}% Store old counter
    setcounter{ALC@rem}{1}% To avoid printing line number
    item //#1 % Display comment + does not increment list item counter
    setcounter{ALC@rem}{arabic{ALC@tempcntr}}% Restore old counter
}%

begin{document} 
        
    begin{algorithm}[!t]
        caption{A sample algorithm.}
        textbf{Input:}  Some input.
        textbf{Output:} Some output.
        
        begin{algorithmic}[1]
            LCOMMENT {1st Step:}
            STATE Do something.
            LCOMMENT {2nd Step:} 
            IF {$A geq B$}
            STATE Do something.
            LCOMMENT {3rd Step:}
            ELSE 
            STATE Do something.            
            ENDIF
        end{algorithmic}
    end{algorithm}

end{document}

which produces the following algorithm. Note that I use a new command for comment (i.e. LCOMMENT) in order to have comments starting with // and, more importantly, to not use line numbering for comments.
However, in the above case, I would like the 3rd comment to have the same indentation as the next line in the algorithm (i.e. line 4) and not the same indentation as line 3. Is there a simple way to do this?

documentclass{article}  

usepackage{algorithm}
usepackage{algorithmic}

newcounter{ALC@tempcntr}% Temporary counter for storage
newcommand{LCOMMENT}[1]{%
    setcounter{ALC@tempcntr}{arabic{ALC@rem}}% Store old counter
    setcounter{ALC@rem}{1}% To avoid printing line number
    item removemargin // #1 % Display comment + does not increment list item counter
    setcounter{ALC@rem}{arabic{ALC@tempcntr}}% Restore old counter
}
makeatletter
newcommand{removemargin}{hspace*{numexpr1-@listdepthrelaxalgorithmicindent}}
makeatother

begin{document} 
        
    begin{algorithm}[!t]
        caption{A sample algorithm.}
        textbf{Input:}  Some input.
        textbf{Output:} Some output.
        
        begin{algorithmic}[1]
            LCOMMENT {1st Step:}
            STATE Do something.
            LCOMMENT {2nd Step:} 
            IF {$A geq B$}
            STATE Do something.
            LCOMMENT {3rd Step:}
IF{x}STATE a LCOMMENT {what?}ELSE STATE b ENDIF % to show further indentation
            ELSE 
            STATE Do something.            
            ENDIF
        end{algorithmic}
    end{algorithm}

end{document}
