Lena is a very curious programmer. She wants to see what files and directories are behind the Hyperskill Code Editor!
Please help Lena write the required code to use the filepath.Walk() function to walk the root directory "." and output the path/name of every file and directory, following this format:
Directory: .
Directory: .bashrc
File: main.go
File: index.html
...
Remember that it is not necessary to output the file size in this task: you only need to print the file and the directory path or the file name!
