What if you have peer failures?After the example above, if N32 fail, but N80 finger table has not been updated, so that the query to the N16, it can not find N32, only N80, so that query will be lost.The workaround is to save R successor instead of just one successor,r is a value that the system can configure.So how big is R? So if there are a lot of errors, query can still arrive correctly.R=2log (N). W.h.p. = with high probabilityWhat to do if file

expressions to find the correct words, by changing the matching string of the regular expression, you can use the same search function to find the words that meet the requirements, in this way, the three functions for searching words can also combine a method to change the matching string for searching words through mode, which is more intuitive and reduces the code length to make the code clearer. You can also use the C # integrated map or dictionary type for word search to reduce the workload

My partner is a very serious student. He has spent a lot of time in his homework. His program ideas are clear and easy to understand. review his code is a relatively happy thing. The program code structure is clear and runs fast. It is a good program to complete basic command requests. However, there are also several areas for improvement:1. Chinese directories cannot be processed.2. The interaction mode does not meet the required requirements.3. You cannot count all files H, CPP, Cs, and TXT. Y

Advantages: 1. There are many annotations first! Feeling warm ...... At the same time, I am ashamed of the code without comments... When writing code, I often do not bother to write comments. When reading other people's code, I always speak out without comments. That's what I do... So I think it's really touching! 2. The structure is clear and the process is easy to understand. 3. There are some basic exception handling methods. Disadvantages: 1. The code is redundant. Write the three mod
