Task

Verify that a file called     input.txt     and   a directory called     docs     exist.



This should be done twice:  

   once for the current working directory,   and
   once for a file and a directory in the filesystem root.


Optional criteria (May 2015):   verify it works with:

   zero-length files
   an unusual filename:     `Abdu'l-Bahá.txt  


import Stdio;
 
int main(){
   if(exist("/var")){
      write("/var exists!\n");
   }
 
   if(exist("file-exists.pike")){
      write("I exist!\n");
   }
}
