问题 This question already has answers here : How do I determine whether an array contains a particular value in Java? (28 answers) Closed last year . I have table of int[] .

问题 I get a return number(0 for success, 1 for failure) form sever made by php so I want get this number to judge my operation succeeded or not. I use this : var str1 :String = NSString(data: d, encoding: NSUTF8StringEncoding)! let str2 = "1" println(str1) // output is 1 println(str2) // output is 1 if(str1==str2){println("same")} //but the two is not same so I debug for this and I get this result: //str1 _countAndFlags UWord 13835058055282163717 -4611686018427387899 //str2 _countAndFlags UWord 1

问题 I have two csv file, A and B. I want to find the number of different column between A and B. For example, let's assume that A contains 7, 9, 0, 0, 2 and B contains 7,8,6,0,2 ( so A and B have five column each). Then, the number of different column is 2, the second and third column. How can I implement this on R? 回答1: You could try indx <- colSums(A!=B) which(!!indx) #gets the index of different columns # Col2 Col3 # 2 3 which(!indx) #gets the index of similar columns #Col1 Col4 Col5 # 1 4 5

问题 I am trying to determine in which way an image has to be cropped to fit perfectly as a square user profile image. I have discovered the Laravel package "intervention image" but as far as I can see this one does not offer a function to compare whether an image is horizontal or vertical. http://intervention.olivervogel.net/ Is there any good way to determine whether the image is a square or horizontal or vertical before resizing and cropping it? This is what I do at the moment: $img->resize(400

问题 I have some questions about string comparison.I couln't find any answers concerning replace and substring methods in particular.So here is the code public static void main(String args[]) { if ("hello".substring(0) == "hello") System.out.println("statement 1 is true"); if ("hello".substring(1) == "ello") System.out.println("statement 2 is true"); if ("hello".replace('l', 'l') == "hello") System.out.println("statement 3 is true"); if ("hello".replace('h', 'H') == "Hello") System.out.println(

问题 I want to make a function, which returns true whenever two numbers provided on input are made up of the same digits (with no replacement). For example, 543 and 435 should return true, 10001 and 11000 should return true, but 111222 and 122222 should return false. I've read something about bitmasks but do not really get it, could You help me? 回答1: The simplest way I can think to handle this is to use buckets. Create an std::vector of length 10 (one for each digit) and then increment an index

问题 If cell A1 contains "Brother Sister Father Mother Grandson" and cell A2 contains "Mother Father", return 2 in cell A3. How can I achieve this? 回答1: Try =SUMPRODUCT(TRANSPOSE(SPLIT(A1," "))=SPLIT(A2," ")) 回答2: For the giving example, this formula entered in A3 should work =sum(ArrayFormula(--regexmatch(split(A1, " "), substitute(A2, " ", "|")))) All depends on how the "real data" is structured. 来源： https://stackoverflow.com/questions/50772870/google-sheets-compare-multiple-words-in-cell-with

问题 Fred here again with a little issue I'm having that I hope you guys can help me with. I'm reviewing for midterms and going over an old file I found on here and I wanted to get it working. I can't find it on here anymore but I still have the source code so I'll make another question on it. So here was his assignment: Write a perl script that will compare two directories for differences in regular files. All regular files with the same names should be tested with the unix function /usr/bin/diff
