split

问题 I am currently working with some files to parse with a Scala app. The problem is that the files are too large so they always end up throwing an exception in the heap size (and I've tried with the max heap size I can and still no use). Now, the files looks like this: This is one paragraph for Scala to parse This is another paragraph for Scala to parse Yet another paragraph And so on. Basically I would like to take all this files and split them in 10 or 20 pieces each, but I have to be sure a

问题 Using JavaScript to split a date and rearrange the format. Date is provided through a json feed as YYYY-MM-DD. To get the date, I do: var og_date = (v.report[totalItems -1].inspection_date); console.log(og_date); console log correctly shows the date, ie "2012-10-01". Next, I try to split the date, for example: console.log(og_date.value.split('-')); And I get: Uncaught TypeError: Cannot read property 'split' of undefined Any ideas? 回答1: Your question answers itself ;) If og_date contains the

问题 I have a vector in R which contains at least 50.000 reals. The values are ordered from small to large and now I need to split up this vector in different vectors. The vector has to be split up when the difference between two numbers is larger than a given number (say two). Example, data <- c(1,1.1, 1.2, 4, 4.2, 8, 8.9, 9, 9.3); # Then I need the following vectors: x1 <- c(1, 1.1, 1.2); x2 <- c(4, 4.2); x3 <- c(8, 8.9, 9, 9.3); The difficulty is that we don't know the number of needed vectors

问题 I need a regular expression that can be used to find the N th entry in a comma-separated list. For example, say this list looks like this: abc,def,4322,mail@mailinator.com,3321,alpha-beta,43 ...and I wanted to find the value of the 7 th entry ( alpha-beta ). 回答1: My first thought would not be to use a regular expression, but to use something that splits the string into an array on the comma, but since you asked for a regex. most regexes allow you to specify a minimum or maximum match, so

问题 (Calculator program)count in one step with math basic order if there is a string = "5+2*6/9"(which is user input) how to get number 2 and 6? i've been trying with split but if there is no '+' it fail :( here is my code atm string[] a = kalimat.Split('*'); string[] a1 = a[0].Split('+'); string[] a2 = a1[a1.Count() - 1].Split('-'); string[] b1 = a[1].Split('+'); string[] b2 = b1[0].Split('-'); ang1 = a2[a2.Count() - 1]; ang2 = b2[0]; angka1 = Convert.ToDouble(ang1); angka2 = Convert.ToDouble
