duplicates

问题 I have been looking for a while how to remove duplicates of my csv files. I started with a file with multiple fields but then I realize that I could just work with one file with 2 field and then merge the files using the first field. Here is what I want to do: I have this file CSV file and as you can see there are genes with more than one description. Some of them have two descriptions, one is "hypothetical protein" and other is "something else". In that case I want to remove the one with

问题 I have a directory with a few hundred txt files. I need to remove all duplicate lines from each of the existing files. Every line in the entire directory should be unique regardless of the file it's in, so I need to compare and check each file against the other. Is this possible to do without altering the existing file structure? The file names need to stay the same. Let's say all the files are in directory "foo" and the total size of the directory is 30mb. I think I can do this through comm

问题 I have a table with primary keys that look like this: FIRSTKEY~ABC SECONDKEY~DEF FIRSTKEY~DEF I want to write a SELECT statement that strips off the segment following the tilde and returns all rows that are duplicates after the post-tilde segment is gone. That is, SELECT ... Gives me: FIRSTKEY~ABC FIRSTKEY~DEF As "duplicates". I already have the bit to strip off the end segment using SUBSTRING: SELECT SUBSTRING(COLUMN, 0, CHARINDEX('~', COLUMN)) FROM TABLE This is on SQL Server. 回答1: The

问题 I use HashMap<String, ArrayList<String>> in Java. When input value is comes, For example, input value is [1, "stack"] , [2, "over"] , [1, "flow"] ..... I want to enter value [1, ["stack", "flow"]] , [2, "over"] in HashMap. But key value is duplicate. So, HashMap was overwrite. So, What can I do? 回答1: Try a Guava Multimap: The traditional way to represent a graph in Java is Map<V, Set<V>> , which is awkward in a number of ways. Guava's Multimap framework makes it easy to handle a mapping from

问题 I have a the following table, it has more columns and is 40 rows long but this is an example of the data. The table is sorted by Team # Data Table I am trying to create a 2nd table that shows the top 10 teams that delivered gears. I want to do this for the other columns as well. I am trying to do this without VBA. I used this function and it worked well: =INDEX(TT_Team,MATCH(LARGE(TT_Tele_Gears,$A3),TT_Tele_Gears,0)) The problem is the duplicate data for the amount of gears delivered IF two

问题 I am able to remove duplicates from either city1 or city2 or city 3 using Muenchian grouping which is key and generate id as shown below. but am not able to remove duplicates by looping into all city1, city2 and city3 Below is the xml <test> <records> <city1>Sweden</city1> <country1>value1<country1> <town1>value2<town1> <city2>Paris</city2> <country2>value1<country2> <town2>value2<town2> <city3>London</city3> <country3>value1<country3> <town3>value2<town3> </records> <records> <city1>Sweden<

问题 Say I have an XML like that: <parole> <parola id="a">1</parola> <parola id="b">2</parola> <parola id="c">3</parola> <parola id="a">4</parola> <parola id="a">5</parola> <parola id="b">6</parola> </parole> Now, I know that the generate-id() function exists. But, for a learning purpose, I would like to know how to change with XSLT the values of the attributes called "id". I've thought about an "algorithm" like: consider the following and the preceding sibling of an attribute. If you meet a

问题 R's duplicated returns a vector showing whether each element of a vector or data frame is a duplicate of an element with a smaller subscript. So if rows 3, 4, and 5 of a 5-row data frame are the same, duplicated will give me the vector FALSE, FALSE, FALSE, TRUE, TRUE But in this case I actually want to get FALSE, FALSE, TRUE, TRUE, TRUE that is, I want to know whether a row is duplicated by a row with a larger subscript too. 回答1: duplicated has a fromLast argument. The "Example" section of

问题 We have a list of product numbers in Excel in a certain order. For reasons I won't get into, we need to highlight when there are duplicates that aren't next to each other.Currently, I'm using this formula in a conditional format to do the job. =AND(COUNTIF($A$2:$A$82,$A2)>1,$A1<>$A2,$A2<>$A3) This mostly works well except in cases where there are pairs of duplicates like in the example below, we would want FO-1694 to be highlighted, because they aren't all next to each other. But we would not
