问题 I'm developing a script which takes the difference between 2 csv files and makes a new csv file as output with the differences BUT only if the same 2 rows (refers to row number) between the two input files contain different data e.g. row 3 has "mike", "basketball player" in file 1 and row 3 in file 2 has "mike", "baseball player". The output csv would grab these print them and write them to a csv. It works but there are some issues (I know that this question has also been asked several times

问题 I'm comparing 2 CSV with the compare-object cmdlet : Compare-object $CSV1 $CSV2 -property Header, Value -passthru | sort-object Header After comparing 2 CSVs, i ended up with the following output : Header Value SideIndicator ------- ----- ------------- String1 Value 1 <= String1 Value 2 => String2 Value 3 <= String2 Value 4 => String3 Value 5 => String4 Value 6 <= I'd like to reorganise it to the following format Header1 Old Value New Value ------ --------- --------- String1 Value 1 Value 2

问题 I have two files (two columns each, split by tab) and I want to compare them based on the first column. If the value on the first column is the same on both files, I want to create a new file using second column values. Also, take into account that IDs in the first column of FILE1 can be duplicated. Basically I have: FILE1: TRINITY_DN10001_c0_g1_i1 TRINITY_DN10001_c0_g1_TRINITY_DN10001_c0_g1_i1_g.84091_m.84091 TRINITY_DN100032_c0_g2_i1 TRINITY_DN100032_c0_g2_TRINITY_DN100032_c0_g2_i1_g.20078

问题 I have an archive system that archives any file (and the corresponding directory structure of where that file is located) to another volume. It ignores empty directories. After the archive has created a copy to an external volume, I've been using the following command to list the differences to make sure that no file has been missed: diff -qr dir1(original) dir2(archive) My problem is that all of the empty directories that the archive system ignores show up and clog the resulting list. Is

问题 I have two list as below: List<Category> categories; List<Category> selectedCategories; and model of Category: (id,catTitle,catId) but I want to compare two list when: selectedCategories:[{id=3, catTitle='first', catId=17},{id=4, catTitle='second', catId=18}] categories: [{id=null, catTitle='first', catId=17} and get {id=3,catTitle='first',catId=17} but when id is null how to have {id=3,catTitle='first',catId=17} as result?!!! 回答1: pubic class Category { Integer id; int catId; String catTitle

问题 I'm trying to find the most frequent word in a list of words. Here is my code so far: uniWords = unique(lower(words)); for i = 1:length(words) for j = 1:length(uniWords) if (uniWords(j) == lower(words(i))) freq(j) = freq(j) + 1; end end end When I try to run the script, I get the following error: Undefined function 'eq' for input arguments of type 'cell'. Error in Biweekly3 (line 106) if (uniWords(j) == lower(words(i))) Any help is appreciated! 回答1: You need to extract the contents of the

问题 My reference is to the binary predicate Compare comp expected in the overload of std::lower_bound etc.: The description reads: The signature of the predicate function should be equivalent to the following: bool pred(const Type1 &a, const Type2 &b); While the signature does not need to have const &, the function must not modify the objects passed to it and must be able to accept all values of type (possibly const) Type1 and Type2 regardless of value category (thus, Type1 & is not allowed, nor

问题 I am trying to compare two dates in this format. date1 = Wed Jul 13 17:23:33 GMT+02:00 2016 date2 = Wed Jul 13 17:23:31 CEST 2016 if(date1.after(date2){ //my logic }else if(date1.before(date2){ //my logic } The comparison seems to have happened only a few times, where it is thought to be wrong? 回答1: tl;dr ZonedDateTime.parse( "Wed Jul 13 17:23:33 GMT+02:00 2016" , DateTimeFormatter.ofPattern( "EEE MMM d HH:mm:ss z uuuu" ) .withLocale( Locale.ENGLISH ) ) .isAfter( ZonedDateTime.parse( "Wed Jul

问题 I have to calculate the values of a hot plate and have it accurate only to the first decimal place. I am stumped on trying to figure out how to check all the array values if they changed. I found out that 724 runs made no change after that to the 4th decimal (how many were being printed). Is there a way to compare doubles variables only up to the n-th decimal place? #include <iostream> #include <string> #include <fstream> using namespace std; const int ARRAY_SIZE = 20; const int NEIGHBORS = 4
