Query: General rogue wave solutions to the discrete nonlinear Schr\"odinger
  equation   In the present paper, we attempt to construct both the general rogue wave
solutions to the fully discrete nonlinear Schr\"odinger (fd-NLS) equation via
the KP-Toda reduction method. First, we deduce the general breather solution of
the fd-NLS equation starting from a pair of bilinear equations. We then derive
the general rogue wave solution by taking a limit to the breather solution.
