points accessed by the find operation. In this way, we can gradually find the perfect match.
It is worth noting that it takes O (N ^ 2) Time to calculate d according to the definition of D above, because D needs to be calculated O (N ^ 2) times, this becomes the bottleneck of the algorithm. It can be optimized as follows: set slack [J] to the minimum value of LX [I] + ly [J]-W [I] [J] for all the edges of vertex J on the right, in the find process, i

Anyone can lose something, what if you lose the root password of your server?
It doesn't matter, we use the following method to recover.
Recovery method
Method One: Directly through the Lilo development init= "/bin/bash start to modify the password method two: through the CD-ROM boot, mount/partition, modify the/etc/shadow file to clear the password
Method One realization process starts Linux first, when Lilo appears, we press a button to let Lilo stop (don't press Enter OH)

This is also true for applications that use slack, especially when used as a very good, customized text input control. You now have a code that is ready to be used in your app.
