Explanations:

• [ -d "$1" ], this checks if its a directory, if yes then run followed printf:

   printf "%s/\n" "${1##*/}" 

else, run below printf:

 printf "%s\n" "${1##*/}" 

• ${1##*/}: this removes longest match of everything * till last slash / seen start from begging of the file/directory path, which it will result only last directory/file name only.
