问题 Here is the situation: I am verifying institution data in a database. Each institution has a code associated with it. I want to be sure that the codes in our database are correct and also check that the names in our database contain no errors. I would do this manually, but there are some 1200 records to check. All my data is contained in a single workbook. The first sheet is the information from our database. The institution name is in column B and the code is in column K. The code is stored

问题 I want to compare 2 text files and output the difference in another text file. $Location = "c:\temp\z.txt" compare-object (get-content c:\temp\hostname_old.txt) (get-content c:\temp\hostname_new.txt) | format-list | Out-File $Location hostname_old.txt server02 server05 server04 server06 server01 hostname_new.txt server04 server01 server02 Results InputObject : server05 SideIndicator : <= InputObject : server06 SideIndicator : <= This is what I want : (get rid of both InputObject and

问题 I am trying to work on a simple data comparison text document. The goal is for the user to be able to select a file, search through this file for a certain parameter, then print those parameters into a new text document, after compare those parameters from the new text document with a text document that has the default parameters and then once they've been compared to print out the differences into a new text document. I've created a simple flowchart to summarize this: This is my current code

问题 how do you setup minimum number of comparisons in general? 回答1: To cite Donald Knuth (by way of Wikipedia, since I don't have my copy of TAOCP at the moment), the lower bound for the number of comparisons is six: http://en.wikipedia.org/wiki/Selection_algorithm (scroll down to the section entitled "Lower Bounds"). Your goal is, effectively, to find the k lowest values where k is half the size of the list, rounded up, (so, k = 3; n = 5) and then take the max of those. Plugging that into the

问题 So, I started with this: http://en.wikibooks.org/wiki/Algorithm_Implementation/Strings/Levenshtein_distance#Ruby Which works great for really small strings. But, my strings can be upwards of 10,000 characters long -- and since the Levenshtein Distance is recursive, this causes a stack too deep error in my Ruby on Rails app. So, is there another, maybe less stack intensive method of finding the similarity between two large strings? Alternatively, I'd need a way to make the stack have much

问题 I found a crude string comparison in a paper I am reading done as follows: The equation they use is as follows (extracted from the paper with small word changes to make it more general and readable) I have tried to explain a bit more in my own words since the description by the author is not very clear (using an example by the author) For example for 2 sequences ABCDE and BCEFA, there are two possible graphs graph 1) which connects B with B C with C and E with E graph 2) connects A with A I

问题 I have a list of intervals, and I need to compare them for overlaps. List<Interval> intervals = new ArrayList<>(); intervals.add(new Interval(dateTime1, dateTime2)); intervals.add(new Interval(dateTime3, dateTime4)); intervals.add(new Interval(dateTime5, dateTime6)); eg. dateTime1 = 2014-06-01 dateTime2 = 2014-07-01 dateTime3 = 2014-08-01 dateTime4 = 2014-09-01 dateTime5 = 2014-08-15 dateTime6 = 2014-09-15 In this case, there is an overlap between the 2nd and the 3rd interval. I can use the

问题 How does the GUI testing tool PyUseCase renamed to StoryText . compare to Dogtail? I want to hear from people who have hopefully experience in using both. Interested in: Maintainabilty of the testing code How well they work against real GUI's? 回答1: Firstly: I'm the author of PyUseCase and I haven't done more than play around with Dogtail... The tools are different in a number of respects. Dogtail works via the accessibility interface under Gnome on Linux, while PyUseCase operates via GUI

问题 I have a basic programming background and have been self sufficient for many years but this problem I can't seem to solve. I have a program in VBA and I need to compare two strings. I have tried using the following methods to compare my strings below but to no avail: //Assume Cells(1, 1).Value = "Cat" Dim A As String, B As String A="Cat" B=Cell(1, 1).Value If A=B Then... If A Like B Then... If StrCmp(A=B, 1)=0 Then... I've even tried inputting the Strings straight into the code to see if it

问题 I am working on E2E tests and my goal is to compare two arrays. I set these arrays so that they are identical. The problem is that Protractor doesn't think they are same. My code: expect(arrPuv).toBe(arrNov); Console output: Error: Expected [ '1 patro', '2. Patro', 'asdf', 'My precious', 'My precious', 'My precious', 'My precious' ] to be [ '1 patro', '2. Patro', 'asdf', 'My precious', 'My precious', 'My precious', 'My precious' ]. How can I compare them correctly? 回答1: This actually goes
