java - How do you recursively replace occurences of a string in an array -

-

Then consider a class A with two string variables "name" and "value"

Class B is a variable that is set 

  set < A & gt; AllVariables   
 is a set that looks like this  
  A.name = "$ var1" value = "x + 10" gt; 2 "A .name =" $ var2 "Evolution =" 11 + y% 10 == 0 "A name =" $ var3 "= values ​​$" var1 "and" $ Var2 "  
 What I need to do is evaluate these expressions. I am using jexl for this to be me through the set and repeat these variable names with their respective Need to change with the values.  
 In this case, the object named $ var3 is named "x + 10" 2 & amp; 11; + Y% 10 == 0 " 
 How do I do this?   
 
 
 2 make the Hashmap,  translated  and  toTranslate .  
 You parse your set.  
 For example, if you see any value, if the value is any number in the  $ element  ( $  sign in), then you can enter  in your translated HashMap keys $ Element .  
 If it's there, then you can search in your translated hash You can replace the  $ element  from the AY value.  
 You do this for each separate  $ element  you found in your object .  
 If all  $ element  has been translated, then add your object A to  translated  hashmap (key = name, value = value). ).  
 Otherwise, you add it to your  toTranslate  hashp.  
 Once all your sets have been parsed, you get 2 hamsps Are there.  
 You create a loop for a while: while  toTranslate  hashp is not empty, then you get each value, and  $ element  translate your   People in Hashp have close  
 Be careful, you can end up with an infinite loop. One good thing will be to make sure that every time you loop on  toTranslate  hash, its number of elements decreases. If you are not in the infinite loop.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
