how do you reverse the order of repeater rows?

I’m trying to sort the rows in the while so that they are 3,2,1 instead of 1,2,3. Would be dope if it could be sorted by $week as it returns a numerical value. I read the ACF page on sorting rows but given I already have some custom code in here to exclude the last row in the while I am not sure how to merge it all.

function smile_gallery( $atts ) {
    if( have_rows('smile_gallery', 3045) ):

    $i = 1;

    $html_out = '';

    $html_out .= '<div class="smile-container">';

        // vars
        $rows = get_field('smile_gallery', 3045);
        $end_row = end($rows);
        $recent = $end_row['smile_week'];
        $count = count( get_field('smile_gallery', 3045) );
        
        $html_out .= '<div class="col-md-6">';
            $html_out .= '<div class="smile-recent">';
                $html_out .= $recent;
            $html_out .= '</div>';
        $html_out .= '</div>';

        $html_out .= '<div class="col-md-6">';
            $html_out .= '<div class="smile-thumbs">';

            while( have_rows('smile_gallery', 3045) ): the_row();

            // vars
            $week = get_sub_field('smile_week', 3045);
            $img = get_sub_field('smile_img', 3045);
            $caption = get_sub_field('smile_caption', 3045);

            // Do stuff with each post here
            if( $i < $count) :

                // vars
                $order = array();
                
                $html_out .= '<div class="smile-thumb-container">';
                    $html_out .= '<div class="smile-thumb-img" style="background: url('. $img .') no-repeat center top; background-size: cover;">';
                    $html_out .= '</div>'; // smile thumb img
                    $html_out .= '<a class="smile-thumb-week" href="' . $img . '" data-lightbox="smile-set" ';
                    if ($caption) :
                        $html_out .= 'data-title="' . 'Week ' . $week . ' - ' . $caption . '"';
                    endif;
                    $html_out .= '><h6>Week ' . $week . '</h6></a>'; // smile thumb week  
                $html_out .= '</div>'; // smile thumb container
            endif;

            $i++;

            endwhile;

            $html_out .= '</div>';
        $html_out .= '</div>';

    $html_out .= '</div>'; // smile container

    endif;

    return $html_out;
}
add_shortcode( 'show_smiles', 'smile_gallery' );
