Program P1482;

var

n, i : longint;

Procedure work;

var

s, us, as : string;

ch : char;

p, dp : longint;

begin

randomize;

readln(s);

us := s;

p := 0;

while (p = 0) and (us '') do

  begin

   ch := us[1];

   delete(us, 1, 1);

   p := pos(ch, us);

  end;

if us = '' then

  begin

   writeln('safe');

   exit;

  end;

as := copy(us, 1, p-1);

dp := p;

p := 0;

while (p = 0) and (as '') do

  begin

   ch := as[1];

   delete(as, 1, 1);

   p := pos(ch, as);

  end;

if p > 0 then

  begin

   writeln('de1ete');

   exit;

  end;

delete(us, 1, dp);

p := 0;

while (p = 0) and (us '') do

begin

  ch := us[1];

  delete(us, 1, 1);

  p := pos(ch, us);

end;

if us = '' then writeln('safe') else writeln('de1ete');

end;

begin

readln(n);

for i := 1 to n do work;

end.

这是程序。。。

大家看看。。
