Why the result of testing is WA?
Here is my program:
 const max=15000;
 var
  a:array[1..max] of longint;
  k:integer;
  f:text;
  procedure readdata;
   var i,m:integer;
   begin
    assign(f,'temp.tmp');
    rewrite(f);
    readln(k);
    for i:=1 to k do begin
     readln(m);
     writeln(f,a[m]);
    end;
    close(f);
   end;{p..readdata}
  function ifp(n:longint):boolean;
   var k:longint;
   begin
     ifp:=false;
     k:=2;
     while (n mod k<>0) and (k*k<n) do k:=k+1;
     if k*k>n then ifp:=true;
   end;
  procedure makep;
   var k:integer;
       p:longint;
   begin
    k:=1;
    p:=2;
    while k<=max do
     if ifp(p) then begin
      a[k]:=p;
      k:=k+1;
      p:=p+1;
     end
     else p:=p+1;
  end;{p.. makep}
 procedure print;
  var i:integer;
      k:longint;
  begin
   reset(f);
   for i:=1 to k do begin
    readln(f,k);
    writeln(k);
   end;
   close(f);
   erase(f);
  end; {p..print}
begin
 makep;
 readdata;
 print;
end.
