(* x3 = StringSplit /@ StringSplit[ xinput, "\n\n" ] *)
(* x4 = Map[ Function[ x, ToExpression[x] ] , x3 ] *)
(* x5 = Map[ Function[ x, Total[x] ] , x4] *)

xresult = Total /@ ToExpression @ (StringSplit /@ StringSplit[ xinput, "\n\n" ])
xAnswer1 = Max[ xresult ]
xAnswer2 = Total @ TakeLargest[ xresult, 3 ]
