Problem Description

Alice is mad over coffee and she loves to try out each type of coffee. She becomes so addictive that she decides to open an online e-commerce website for premium coffee beans. To start with, she goes online and learns about various species of coffee available. She starts saving description of each type and starts writing it down in .txt files named like {SPECIES_NAME}.txt. For e.g. description of Arabica will be stored in Arabica.txt. For each type of species, she maintains exactly one text file.

She also keeps downloading images she comes across. All the images she downloads, contains the name of the species of the coffee separate by hyphen character -. For e.g. for arabica it can be something like 30sdfknl09123-arabica-23ij09d67as5123.png. It is guaranteed that the file names have only 2 - characters and she only downloads images for which she has already noted down the description in a .txt file.

She is so involved that she forgots to arrange her files. All of the files have been downloaded in the same folder. We need to help her rearrange the files like the following dirctory hierarchy in the same folder:


where {species} is the name of the coffee species. All images are moved under images folder of the respective species folder and description is moved under about folder of the respective species folder with the name desc.txt

We need to provision her with an executable that helps her arrange the files.
