   Goal
   I wan to display previous / next category name on post.

   Example
   Category1 Category 2 Category 3
   Post 1 Post 4 Post 7
   Post 2 Post 5 Post 8
   Post 3 Post 6

   Let say I have a data like this and went to post 5.
   I want to detect what category the post 5 is then calculate +, - and display the Category 1 name and Category 3 name.

   Able to figure it out.

   <?php
       $categories = get_the_category();
       $separator = ' ';
       $output = '';
       if($categories){
           foreach($categories as $category) {
               $prev_step .= '<a href="'.get_category_link( $category->term_id-1 ).'" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '" class="previous-step">'.get_cat_name( $category->term_id-1 ).'</a>'.$separator;
               $next_step .= '<a href="'.get_category_link( $category->term_id+1 ).'" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '" class="next-step">'.get_cat_name( $category->term_id+1 ).'</a>'.$separator;
   		}
   	}
   ?>
   
   <?php echo trim($prev_step, $separator);?>
   <?php echo trim($next_step, $separator);?>
