The title of this article refers to the processing of a page that has generated HTML before it is output to the client.The principle of the method is: Redirect the output of response to the custom container, that is, our StringBuilder object, in the HTML all the page output to the StringBuilder output, Then we finish the StringBuilder processing, then redirect the output of response to the original page, an

Text ReverseProblem Descriptionignatius likes to the write words in reverse. Given a single line of text which are written by Ignatius, you should reverse all the words and then output them.Inputthe input contains several test cases. The first line of the input was a single integer T which is the number of test cases. T test Cases follow.Each test case contains a, with several words. There'll is at the most of characters in a line.Outputfor Each test case, you should the output of the text which

increased or decreased when the maximum flow is obtained, therefore, after processing the maximum stream, a forward edge with Zero traffic will appear (the program will ask what to say to the forward edge ), however, an edge similar to 0-> 0-> 0 appears... Therefore, it is excluded that this is not the only side on this road, and the number of other sides with 0 is the desired value. Here, we can search th
