(4) Replace an output file and go back to step (2) Explanation: During the operation of the above algorithm, step (3) each from the minimum heap output a minimum value, from the input file is read into a data, if the number of new reads than the number of just output, you can belong to the current string, put it into the heap, otherwise it can only belong to the next straight string, need to put it outside the heap, in the process of running, The size of the heap is gradually reduced to 0, and

Label:To insert a value into an AutoNumber (or identity column, identity), you need to set the SET Identity_insertExample:1. First create a table with an identity column:CREATE TABLE products (id int IDENTITY PRIMARY KEY, product varchar (40))2.

Watir is an open-source Web automation testing framework implemented using Ruby. Compared with those large commercial tools, watir is small, flexible, and provides sufficient functions. Recently, I took the time to try it out. I feel pretty good. I plan to use it in the company for further promotion. The user manual, sample code, and FAQ on watir are well maintained, so I will not repeat the existing items. Here, I will briefly introduce them. If you are interested, you can study it together. 1.

the thread pool to show the number of available threads in the thread pool: getavaliablethread (Out workerthreadcount, out iocompletedthreadcount). For me, the first time I saw this function parameter, it was very confusing, because I expect this function to directly return an integer indicating the number of threads left, this function returns two variables at a time. The threads in the original thread pool are divided into two categories by public: worker threads and IO threads, Or Io complet

. First, check the feasibility of Solution A. Use SOCKET to simulate IE to access the website and parse the http package. The workload is heavy.The B solution has no clue yet. You can only remember an Excel example when accessing the COM interface in ruby. So Google found that watir (web application testing in ruby) is an open-source framework used to automatically test web applications.The principle is to use the COM interface of IE to manipulate some behaviors of IE. Exactly what I need. First
