Problem of the Day
A new programming or logic puzzle every Mon-Fri

Welcome back to another awesome Monday!

We'll start the week off with a simple one. Today's problem is to create a program that takes in a directory on your computer and outputs the files and folders in that directory. Bonus points for differentiating between files and folders in your output.

      static void GetFilesAndSubDirs(string strPath)
      {
          System.IO.DirectoryInfo objDirInfo = new System.IO.DirectoryInfo(strPath);
          System.IO.FileInfo[] aryFiles = null;
          System.IO.DirectoryInfo[] arySubDirs = null;
          aryFiles = objDirInfo.GetFiles();
          if (aryFiles != null)
          {
              foreach (System.IO.FileInfo objFile in aryFiles)
              {
                  Console.WriteLine(String.Format("File: {0}", objFile.FullName));
              }
              arySubDirs = objDirInfo.GetDirectories();
              foreach (System.IO.DirectoryInfo objSubDirInfo in arySubDirs)
              {
                  Console.WriteLine(String.Format("Directory: {0}", objSubDirInfo.FullName));
                  GetFilesAndSubDirs(objSubDirInfo.FullName);
              }
          }
      }

  #python 2.7
  import os
  
  for dirname, dirnames, filenames in os.walk('.'):
      # print path to all subdirectories first.
      for subdirname in dirnames:
          print "<Dir> \t" + os.path.join(dirname, subdirname) 
  
      # print path to all filenames.
      for filename in filenames:
          print "<File> \t" + os.path.join(dirname, filename)
