, according to the target type, if the flow is $f$, then the cost is $f^2$, the solution is to connect the capacity 1 of the cost is 1, 3, 5, 7, 9 ... 's Side!

Exercise:
4. It is proved that the subgroups with an exponent of $2 $ must be regular.
It is proved that if $ G $ is set as a group and $ H is
$ G = H \ cup ah, A \ notin h $
There must be right companion set decomposition.
$ G = H \ cup ha $
Obviously, $ Ah = ha $. We know $ H \ lhd g $ from the arbitrary representation of the equivalence class.
5. Set $ G $ as a group, $ H \ LHD g, k \ lhd g $, and $ H \ cap K =\{ e \} $. Proof
$ HK = KH, \ forall

This is a basic network stream question. I haven't written any network stream for a long time. At first, I assigned the cap [v] [u] to the-cap [u] [v], as a result, WA has been used for many times. It seems that it is mixed with the cost [v] [u] =-cost [u] [v] of the largest flow with the minimum cost.

DashPathEffect (new float [] {30, 10, 20, 10}, 0 ); // corner inflection point path CornerPathEffect cornerPathEffect = new CornerPathEffect (50); // The merged path SumPathEffect sumPathEffect = new SumPathEffect (ignore, cornerPathEffect); // you can specify the path paint. setPathEffect (sumPathEffect); canvas. drawPath (path, paint );
We can see the effect of overlapping a dotted path and a circular corner path.

The Heapbytebuffer heap byte buffer is the allocation of buffers to the heap heap in the JVM, whose implementation itself is a byte array, actually the user memory in the operating system, not kernel memory.

Asynchronous replication: Unlike a RAID storage system, replication in NoSQL is often a log-based asynchronous replication. In this way, the data can be written to a node as soon as possible without being delayed by the network transmission. The disadvantage is that consistency is not always guaranteed, and a small amount of data may be lost in the event of a failure.
Base: The NoSQL database guarantees the base attribute relative to
