IRP dispatching and handling
If a dispatch routine returns status_pending, the IRP passed intoDispatch routine must be marked pending with iomarkirppending ().
If an IRP is marked pending with iomarkirppending () in a dispatch routine,That dispatch routine must return status_pending.
If an IRP is to be marked pending, iomarkirppending must be called beforeThe IRP is ac
We need to enumerate the root and then choose as many points from its subtree as possible and pay no more than M, but the complexity of the violence is not right.Then consider merging the tree from bottom up (there is only one node in each tree, which is itself)Each tree is a heap, we maintain the number of nodes in the tree and the sum of the salaries, and when combined, the top salary of the heap is constantly popped up until the sum of the salary does not exceed m, then the answer is updated
of C discretization after the block (note is the weight C instead of the sequence s), for the non-modified interval query with the team to transfer, the weight of the block is O (1), the query is O (sqrt (n)), the complexity is still O (n*sqrt (n)).The next step is the detail question. We first DFS to find the DFS sequence and after the interval sort (with the left end of the block as the first keyword, the right end as the second keyword), and then the tree nodes according to the size of C, th

. In the future programming we will continue to improve our normative writing and code algorithm effectiveness and so on.
Experience and summary of programming process
Through two weeks of time, although the final rough finished the knot on the work, but the harvest is heavy, this programming brings me a kind of different experience, let me feel the importance of cooperation, in programming there are many times our opinion is not agreed to add each person's code style and norms are
handover work is not know what the variable represents the meaning, but the mouth to their own requirements are particularly strict, Always make the code as clear as possible. This is the place where I need to learn. At the beginning of the code test I was not too familiar with the help and encouragement of the mouth to gradually adapt to the job.
Initial completion of work: Due to time is more tense, our task can only be said to be preliminary completed, and did not take into account the e
throughout the process, our procedures are improved step-by-step, until the final molding, without the exchange of discussions between each other, but also to both sides have learned a lot of new knowledge. Our cooperation in this pair of programming projects is very enjoyable. Although the final finished product does not fully meet all requirements, but this project is important to let a beginner Java I consolidated a lot of basic knowledge and also learned a lot of new knowledge, I believe th
For this pair of tasks, because themselves are not in school, so there is no good way to communicate with my teammates, so my task is to establish the implementation method, and proposed algorithm, here very grateful to my two teammates, they are very responsible, as a team, very good to complete the task here, To exert their own power to the maximum.The feeling of this task is that they used to be a person to do a program Ah, task Ah, very few and one or a few people to carry out such cooperati

The road to the disaster area is full of landslides,70% above the road damage, the bridge is all destroyed. The state immediately launched emergency preparedness plans, the history of the largest non-combat air transport operations, ready to drop urgently needed supplies to the disaster area. one side has difficulty , p plus
