string-split

问题 I know how to split a list of strings into a nested list using those strings, but I'm not specifically sure how I would go about splitting those strings now into multiple strings. For example: def inputSplit(file_name): with open(file_name) as f: content = f.read().splitlines() i = 0 contentLists = [content[i:i+1] for i in range(0, len(content), 1)] Would give me something like: [['these are some words'], ['these are some more words'], ['these are even more words'], ['these are the last words

问题 What is the best way to split some given larger number into hundreds, tens and units in C#? For example: If I enter number 43928 how can I get 40000 + 3000 + 900 + 20 + 8 on the output? 回答1: Something like this: long x = 43928; long i = 10; while (x > i / 10) { Console.WriteLine(x % i - x % (i / 10)); i *= 10; } it will give you output 8 20 900 3000 40000 回答2: You have to use the % operator. Example: 43928 / 10000 = 4; 43928 % 10000 = 3928; 3928 /1000 = 3; 3928 %1000 = 928, etc... 回答3: Linq

问题 I'm looking for a way to split string by multiple delimiters using regex in C++ but without losing the delimiters in output, keeping the delimiters with splitted parts in order, for example: Input aaa,bbb.ccc,ddd-eee; Output aaa , bbb . ccc , ddd - eee ; I've found some solutions for this but all in C# or java, looking for some C++ solution, preferably without using Boost. 回答1: You could build your solution on top of the example for regex_iterator. If, for example, you know your delimiters

问题 public static void main(String[] args) { // TODO Auto-generated method stub String str="aaabbddaabbcc"; String[] str2=str.split(""); String pointer=str2[0]; int count=0; String finalStr=""; for(String str132:str2) { if(str132.equalsIgnoreCase(pointer)) { ++count; } else { finalStr+=str132+count; count=0; pointer=str132; ++count; } } System.out.println(finalStr); } On performing a str.split("") , why am I getting a "" in the 0th index of the str2 array? 回答1: why am i getting a "" in the 0th

问题 I have the following SQL script: DECLARE @temp table ( ID int IDENTITY(1, 1), data nvarchar(100) ) INSERT INTO @temp (data) VALUES ('a,b,c') INSERT INTO @temp (data) VALUES ('d,e,f') SELECT * FROM @temp AS T INNER JOIN (SELECT * FROM dbo.__StringSplit(T.data, ',', T.ID)) AS S ON T.ID = S.RefID And on after clicking !Execute, I got these: Line 17 The multi-part identifier "T.data" could not be bound. I have also tried the non-join version and got the same error: SELECT T.ID, S.Item AS dataItem

问题 I have string like this: str:='ac_Abc.88,ac_Abc.99,ac_Abc.77'. I need to get first element after splitting with comma(,). So im using using like this: str VARCHAR2(500); dbms_utility.comma_to_table ( list => regexp_replace(str,'(^|,)','\1') , tablen => l_count , tab => l_array ); I'm getting following error: ORA-20001: comma-separated list invalid near bc.88 ORA-06512: at "SYS.DBMS_UTILITY", line 239 ORA-06512: at "SYS.DBMS_UTILITY", line 272 But if i have string like this, str:='ac_Abc88,ac

问题 An incredibly basic question in R yet the solution isn't clear. How to split a vector of character into its individual characters, i.e. the opposite of paste(..., sep='') or stringr::str_c() ? Anything less clunky than this: sapply(1:26, function(i) { substr("ABCDEFGHIJKLMNOPQRSTUVWXYZ",i,i) } ) "A" "B" "C" "D" "E" "F" "G" "H" "I" "J" "K" "L" "M" "N" "O" "P" "Q" "R" "S" "T" "U" "V" "W" "X" "Y" "Z" Can it be done otherwise, e.g. with strsplit() , stringr::* or anything else? 回答1: Yes, strsplit
