split

问题 This question already has answers here : String.split() *not* on regular expression? (8 answers) Closed 5 days ago . In my Java application I need to find indices and split strings using the same "target" for both occasions. The target is simply a dot. Finding indices (by indexOf and lastIndexOf) does not use regex, so String target = "."; String someString = "123.456"; int index = someString.indexOf(target); // index == 3 gives me the index I need. However, I also want to use this "target"

问题 Working on a program that uses RPN (Reverse Polish Notation). I have a function that reverses all the words of string without using strtok or triggering printf (unlike all the solutions found online and here). The function actually works partially as it prints all the words of a given string except the last one and I need help figuring out what's going on. char *extract(char s[]) { if (s[0] == '\0') return NULL; int i = 0; char *p = NULL; while (s[i] != '\0') { if (s[i] == ' ') p = s + i; i++

问题 Hi I have a dataframe that follows this format: df = pd.DataFrame(np.array([[1, 2, 'Apples 20pk ABC123', 4, 5], [6, 7, 'Oranges 40pk XYZ123', 9, 0], [5, 6, 'Bananas 20pk ABC123', 8, 9]]), columns= ['Serial #', 'Branch ID', 'Info', 'Value1', 'Value2']) Serial# Branch ID Info Value1 Value2 0 1 2 Apples 20pk ABC123 4 5 1 6 7 Bananas 20pk ABC123 9 0 2 5 6 Oranges 40pk XYZ123 8 9 I want to split the "Info" column's values based on the "pk" character. Essentially, I want to create two new columns,

问题 I'm trying to split the values of a csv file into separate lines using the delimiter=, as a point to split from. i.e. #csv file video1,video2,video3 video4,video5,video6 #Preferred output: video1, video2, video3, ect.... So far I have: @echo off setLocal EnableDelayedExpansion for /f "tokens=* delims=, " %%a in (input.csv) do ( set /a N+=1 echo ^%%a^,>>output.csv ) However I run into the issue of parameter %%a just being added as a string. How would I cause a split instead for each , and put

问题 I have completed an origin-destination cost matrix (23 origins, ~600,000 destinations) for traveling through a street network in ArcGIS and disaggregated the resulting matrix into DBF tables by store ID using a Python script. I have loaded each DBF table into an R session as follows: # Import OD cost matrix results for each store origins <- read.dbf('ODM_origins.dbf') store_17318 <- read.dbf('table_17318.dbf') store_17358 <- read.dbf('table_17358.dbf') store_17601 <- read.dbf('table_17601.dbf
