+// EXERCISE: Path Searcher
+//
+//  Your program should search inside the path environment
+//  variable.
+//
+//  Remove the corpus constant then get the corpus from the
+//  environment variable "Path" or "PATH" which
+//  constains paths to the executable programs on your
+//  operating system.
+//
+// HINTS
+//  1. Search the web for what is an environment
+//     variable and how to use it, if you don't know
+//     what it is.
+//
+//  2. Look up for the necessary function for getting
+//     an environment variable. It's in the "os" package.
+//
+//     Search for it on the Go online documentation.
+//
+//  3. Look up for the necessary function for splitting
+//     the path variable into directories. It's in
+//     the "strings" package.
+//
+// EXAMPLE
+//  For example, on my Mac, my PATH environment variable
+//  looks like this:
+//
+//    "/usr/local/bin:/sbin:/Users/inanc/go/bin"
+//
+//  So, if the user runs the program like this:
+//
+//    go run main.go /sbin
+//
+//  It should print this:
+//
+//    #2 : "/sbin"
+// ---------------------------------------------------------
+
+// ---------------------------------------------------------
+// BONUS EXERCISE
+//  Make your program cross platform. So, it can search
+//  the path environment variable when you run it on
+//  a Windows or on a Mac (OS X) or on a Linux.
+//
+// HINT
+//  1. What you're looking for is the runtime.GOOS constant.
+//  2. Get the operating system name using GOOS.
+//  3. Adjust the path environment variable name and
+//     the directory separator accordingly.
+//
+//  FOR EXAMPLE: On OS X, path environment variable's name
+//    is PATH and the separator is a colon `:`.
+//
+//  Or, on Windows, its name is Path and the separator is
+//    a semicolon `;`.
