One of the biggest advantages of using ADODB is that, regardless of the backend database, the methods for accessing the database are the same, so developers do not have, however, you must learn another set of different access methods, which greatly reduces the knowledge burden on developers. The previous knowledge can still be used in

The number of cyclic sections in this case is N/2, and the situation is also N/2 species.The data range of the two problems is very small, so it is possible to deal with this directly.　　　Program poj1286;varI,n:longint; Tot,sum:int64; w:array[-1.. -]of int64;function gcd (x,
