Title. and the number of requests that are behind this-n refers to the number of users? Means: When 10 users request a server, there may be 1 concurrent or 1-10 concurrent, or maybe 0 concurrent? Ab-n 10-c 1 http://localhost/a

I took the book Java confusing again from the library. Now I want to repeat it again. Unlike reading this book in my junior year, I decided to take some notes. Take some time every day to read some puzzle to make the dull brain clearer. When reading every puzzle in this book, it feels like Fan Wei's Role in the sketch, it is often said that "this is the case ". However, the difference is that reading puzzle makes people smarter, rather than being fooled. So I decided to write a series and read i

1. Problem description In large-scale data processing, often encountered a kind of problem is to find the highest frequency of the largest number of top K, or from the mass of data to find the maximum number of the first k, such problems are commonly referred to as "top K" problem, such as: In search engines, statistical search the most popular 10 query words , in the song Library, the highest download rat

Question: It is known that a function rand7 () can generate a random number ranging from 1 to 7. Please provide a function that can generate a random number ranging from 1 to 10. Ideas: If we know that a function can generate a random number ranging from 1 to 49, how can we generate a random number ranging from

As early as itpub saw a SQL expert, like the puzzle, the following is a puzzle.

10. Dynamic Planning (3) -- 0-1 backpack problem, 0-1 backpack In the previous article "9. Dynamic Planning (2) -- Subsets and problems", we talked about Subsets and problems and their implementations. Backpack problems are actually a subset and a type of problem, but the problem is not "determining the problem" but "optimal problem ". The problem with a backpack

Random Number problem-it is known that there is a Random7 () function, returns a random natural number from 1 to 7, so that the Random7 () is used to construct a random 1 ~ Random10 ~ 10. random7random10 Math. random () randomly generates the float number between (0, 1), and Random7 randomly generates an integer betwe
