Test instructions is easy to understand: Limak can give their own balloons to others, so that other people's balloons than weight. Thus allowing others to float on the ceiling, unable to participate in the rankings, thus making limak their rankings rise. This topic is a typical greedy, when limak his own balloon to others, his own hands of the balloon will be reduced, then his own ranking is likely to be re

The idea of the problem is very difficult to think about. Asking the minimum number of experiments you need is very difficult to solve. And we know that there are only three conditions. K, N, number of experiments.So we'd better change our mind and turn to the highest number of floors we can determine. Then use D[I][J] to indicate the maximum number of floors that can be determined with the I-ball and the J-time of the experiment.So if we're on the K-floor, there are two possibilities: 1, the ba

This tutorial uses Photoshop to draw the lovely balloon WordArt tutorial, the production of balloons is relatively cumbersome, because the high light and dark areas are not very regular, not directly with the layer style to complete, you need to use a pen to check out the outline of each part, into the selection after the corresponding color fill.

How do I know I'm done with IO?first, the event-driven model introductionTypically, when we write a program that server processes a model, there are several models: (1) Each time a request is received, a new process is created to process the request;(2) Each time a request is received, a new thread is cre

, nonblocking I/O, and I/O multiplexing models are synchronous I/O models, because in the process of waiting for the data, the processes in these three models do not do anything else, even if the non-blocking polling can be considered as a synchronization. The book also argues that the signal-driven I/O model is synchronous I/O, which says that POSIX defines the synchronous IO operation as "causing the request process to block until I/O operation is c

Background: Pio DMA interrupt polling The speed of early I/O devices is not too high compared with that of CPU. The CPU periodically polls the IO Device once to see if there are any processing requirements. If yes, it will be processed and then return to continue working. So far, the floppy disk still keeps this round robin method.With the rapid increase in CPU performance, this inefficient way of working wastes a lot of CPU time. As a result, interru
