你用掐时撒！

I got Compilation error or Crash (at #test 5 access violation),but my program is so quickly!

URAL到底是什么呀？谁能告诉我？

一个在线题库，但题型不象USACO那样分级排列~~~so~~做起来很自然~

但不适合专题训练~

偶的弱程序：
用的类似背包问题的算法。



var tt,top,k,b:int64;
  i,j,x,y:longint;
  q:int64;
  a:array[0..32]of longint;
  f:packed array[0..1000000000]of boolean;
  total:packed array[0..1000000000]of byte;

begin
read(x,y,k,b);
q:=1;
top:=0;
repeat
a[top]:=q;

inc(top);
q:=q*b;

until q>y;
dec(top);

f[0]:=true;
total[0]:=0;

tt:=0;

if k<>1 then
for i:=0 to top do
begin
  for j:=y downto a do
  if total[j]<k then

  if ((f[j]=false)and(f[j-a]=true))
    or((f[j]=true)and(f[j-a]=true)
    and(total[j-a]+1<total[j])) then
    begin
    f[j]:=true;
    total[j]:=total[j-a]+1;
    if (total[j]=k)and(j>=x) then inc(tt);

    end;
end
else
begin
for i:=0 to top do
  if a in [x..y] then inc(tt);
end;

writeln(tt);

end.
