Gold Transportation Time Limit: 2000MS Memory Limit: 65536K Total Submissions: 2995 Accepted: 1065 DescriptionRecently, a number of gold mines has been discovered in zorroming state. To protect this treasure, we must transport this gold to the storehouses as quickly as possible. Suppose the zorroming state consists of N towns and there is M bidirectional roads among these towns. The gold

2000-ton number is special, which is exactly twice the transportation volume of trains and is just a complete number. The problem is: how far can 2000 tons of coal be consumed by 1000 tons at most? We know that 2000 tons of coal need to be set off twice by train, plus the return time in the middle, three times in total (no return is required after the last departure), that is, how far the 1000-ton coal train can run three times, 1000/3 meters.

As we all know, network data transmission between different hosts is mainly completed through the TCP/IP network protocol. This is true for enterprise LAN data transmission and Internet data transmission. However, it is hard to figure out that no security was provided during the design of the TCP/IP protocol. That is to say, the TCP/IP protocol alone cannot guarantee the secure and stable transmission of data in the network. Therefore, the security of data in the network depends on high-level ap

Oracle Tablespace Transportation premise: the user must have SYSDBA system permissions for Tablespace transmission. The moved Tablespace is a self-contained Tablespace and should not depend on the existence of objects of external Tablespace objects. Determine whether to include the data. You can use the TRANSPORT_SET_CHECK process in the system package DBMS_TTS to check whether the data is transmitted to the table space OLTP. For example, you can use
