how to use a vertex to update its son, and so on.\(\,\,\,\,\,\,\,\,\,\,\,\)The root value is very good, because you only need to go down. Consider how to update your son. \(\,\,\,\,\,\,\,\,\,\,\,\)For example, the string length of each vertex is equal to its own number. We first pre-process the total length from the 1st point to all the leaf points, and then consider updating the 7th point. For all the leaf points in the idea tree No. 7, point 1 must first Access Point 7 and then go down to ac

Http://poj.org/problem? Id = 2018 Given the number of N, you can find the interval with the maximum length equal to or greater than the average value of F. This topic is described in detail in this paper. Let's take a look at this article. I will explain the key steps. 1: The sum of a range can be expressed as (s [B]-s [A-1])/(B-A + 1), similar to the slope of two points, that is(A-1, s [A-1]) (B, s [B])The slope of two points can be expressed.[

lower layer. Due to locality, writing back can significantly reduce bus traffic.The disadvantage is increased complexity.Another problem is how to deal with write Miss.Write allocation: load the corresponding lower-level block to the cache, and then update the cache block. The disadvantage is that each Miss will cause a block to be transferred from the lower layer to the cache.Non-write allocation: Avoid high-speed caching and write the word directly to the lower layer.Performance impact of hig

: Soft text promotion methodSoft text promotion is a kind of smooth and silent promotion method, the app can also be used to promote the promotion of soft text, the most common way to rub hot spots, the purpose of the application to promote the combination of hot topics, so as to attract more people to read, the reader has a subtle impact, digging out the reader species hidden customer groups.Method VII: Community Promotion methodCommunity is a more active group, can choose their own target comm

library to invoke the API to implement the requirements, and the process is completely black-box. The goal of reverse engineering is to open the box and use some tools to start with a binary level, which in turn guesses the application developer's code and logic. This will involve a lot of C language, operating system, compiling the principle of things, relatively high threshold. Reverse engineering is also a big value for businesses because they don't want to be seen by rivals and interested i
