find

问题 I am using an STL queue to implement a BFS (breadth first search) on a graph. I need to push a node in the queue if that node already doesn't exist in the queue. However, STL queue does not allow iteration through its elements and hence I cannot use the STL find function. I could use a flag for each node to mark them when they are visited and push them only when the flag is false, however, I need to run BFS multiple times and after each time I will have to reset all the flags, so I ended up

问题 Is it possible to somehow pass multiple strings to the string::find function? For example, to find a string I might use this: str.find("a string"); What I'd like to do is something like this: str.find("a string" || "another string" || "yet another string") And have the function return the position of the first occurrence of any of the three strings. Thanks for any suggestions. 回答1: Not with std::string::find , but you could use std::find_if from <algorithm> : std::string str("a string"); std:

问题 I have an array of points or locations that are scattered throughout a big matrix, and I have a small bounding box inside the matrix. I need a way to check if the points in the array are within the bounding box. Thanks for your suggestions. BoundingBox = [BB1,BB2,BB3,BB4]; Array = [x1,y1;x2,y2;x3,y3;x4,y4;x5,y5;x6,y6]; I have tried ismember([BB1,BB2,BB3,BB4],Array); and ismember(rectangle('Position',[BB1,BB2,BB3,BB4]),Array); but nothing is working 回答1: You should read ismember()'s

问题 I'm writing a generic crud service I'm trying to implement the Get method with an optional virtual method to include properties However I'm having some trouble because FindAsync is only declared on a DbSet : public async virtual Task<TDTO> Get(object[] id) { // I want to do something like this var entity = await this.ApplyGetIncludes(this.GetEntityDBSet()).FindAsync(id) return this.AdaptToDTO(entity); } protected virtual DbSet<TEntity> GetEntityDBSet() { return this._context.Set<TEntity>(); }

问题 Need help in understanding this complex Unix find command and its operation: find . \( \! -user xx -exec chown -- xx '{}' + -false \) -o \ \( \! -group root -exec chgrp -- root '{}' + \) -o \ \( ! -perm 700 -exec chmod -- 700 '{}' + -exec false \; \) Also, I am looking out in particular the purpose of -false predicate. I guess I mixed both GNU and non-GNU find syntax 回答1: The false predicate evaluated to false for -o and it is used here to prevent short short-circuiting. if user is not xx

问题 Morning all, I'm trying to work out how to go into a number of text files within a directory, and replace the characters with the following: 'BS' = '\' 'FS' = '/' 'CO' = ':' What I managed to get to so far is: (get-content C:\users\x\desktop\info\*.txt) | foreach-object {$_ -replace "bs", "\"} | set-content C:\Users\x\desktop\info\*.txt I have got 6 text files, all with a line of text in them, the script above copies the line of text into all the text files. So what I end up with is 6 text
