To answer your questions:

• Get the string stored in $1; use it as the key into a hash named %qq; print the value of that hash element. There should only be one value, by definition.
• Revised:Get the number stored in $1; use it as the index into an array named @qq; print the value of that array element. There should only be one value, by definition.
• Try this (though, since this is either homework or an exam, I may be playing with your head. Good luck...):

  if ( /^(\d*).+(\d*)$/ )
      {
  #      $1 containing the starting numeric string, if any.
  #      $2 contains the terminating numeric string, if any.
      }
