问一下:这道题若要硬算出必败数列中的每一项,则必超时?

Posted by 15pengyi at 2005-04-10 16:35:11 on Problem 1067
可以不代公式么?
这个程序对么?
program pku1067;
const max=15000;
var a,b,c,d,i,j:longint;
    f:array[0..max] of longint;
begin
   while not seekeof(input) do
   begin
      fillchar(f,sizeof(f),0);
      readln(a,b);
      if a>b then begin  c:=a;  a:=b;  b:=c; end;
      f[1]:=1;  c:=1;  d:=1;  i:=1;  j:=1;
      while (f[c]<a)and(c<b-a) do
      begin
         while f[i]=d do begin i:=i+1; d:=d+1; end;
         while f[j]+j=d do begin j:=j+1; d:=d+1; end;
         c:=c+1;
         f[c]:=d;
      end;
      if (f[c]=a)and(f[c]+c=b) then writeln('0') else writeln('1');
   end;
end.
就是硬产生必败数列中的每一项,若不在这个数列中的,则为必胜?
