Since nothing in JavaScript specification says length must be exactly one higher than the last index, your demand is not reasonable. In common use, dense arrays overwhelmingly outnumber sparse ones. Since JavaScript does not keep indices in an ordered structure, finding out which index is the last every time array contents change would incur a … Read more
You should have setArray defined- methods function setArray(h) %% code end end solved MATLAB: Undefined function for input arguments [closed]
ok, so you are allowed to use charAt which you can use to find the spaces between words. When you know where the spaces are you can use substring to isolate the individual words and store them in variables. Then you can move them around and join them back together. So as an example: var … Read more
The error message give you a big hint where to look: Undefined operator ‘+’ for input arguments of type ‘cell’. Error in gbp2/pts (line 36) ylist(z) = ylist(z) + arrayfun(@(coor) u(z, coor, mode, w, R, Psi),xlist(z).’,’uniformoutput’,false); From the documentation for arrayfun and the ‘UniformOutput’ option: Requests that the arrayfun function combine the outputs into cell … Read more
SELECT meta_value FROM tablename WHERE meta_key = first_name SHould do the trick! What we are doing is selecting the value in the meta-value column if the meta_key column says ‘first_name’ You can do the same for all fields SELECT meta_value FROM tablename WHERE meta_key = admin_color Would return ‘fresh’ from your screen-shot. 2 solved Weird … Read more
You could take an array for the wanted groups and related keys and take an iterative and recursive approach. var data = [{ _id: “5c407834953d7f420d56f866”, allocated_to: “FIELD”, zone: “NORTH”, state: “DELHI”, location: “NEW DELHI”, customer_name: “REET INFOTECH”, bank_name_of_customer: “YES BANK”, cl_contract_id: “LAI-00016881”, lk_loan_account_id: “LK0000015094”, front_end_manager_name: “SONAL”, area_collection_manager: “ASHIS JENA”, installment_date: “”, collection_manager: “” }, { … Read more
Let’s suppose you run with libjpeg. You’ll allocate a buffer and then call jpeg_read_scanlines a sufficient number of times to get all of your decompressed image data into memory. You can read scanlines (rows) individually and reformat them as needed. If the image is grayscale, the RGB values will all be equal, so you can … Read more
Using flatMap you can ungroup the elements in an array.. const fruit=”apple” const array=[ { names:[‘something1’, ‘something2’], fruit: fruit, features:[‘feature1′,’feature2’] } ] array.flatMap(({names,fruit,features}) => { names.flatMap(name => { features.flatMap(feature => { console.log(({name,fruit,feature})); }) }) }) 5 solved Creating objects by splitting an object whose attributes are arrays [closed]

A contains numbers while B contains strings. You want to cast to numbers first to make the computation, and then cast the result to string to get a string; you can use .toFixed to get a given number of precisiong (according to your expected output). A = [ 25.8, 27, 24.099999999999998, 30.070000000000004, 34.3, 34.300000000000004, 34.3, … Read more
A Set is not what you want, because: Sets only hold unique values The elements of a Set have no order, so you can’t access elements by index A better choice is a List, such as an ArrayList, which allows any (ie duplicate) values and can be accessed by index using list.get(i). 2 solved Get … Read more
Check if there’s a whitespace (\s) before or if it’s the start of the string (^). (?:\s|^)@.* Live Demo If you only want to match word characters, then instead of using . you could use \w. Also note that * would still match just “@”, so you might want to use + instead to match … Read more
+— arr[2] | v let arr = [1, 2, 3]; <—— arr.length = 3 console.log(arr.length + arr[2]); ^ | +– arr at index 2 returns 3 let arr = [1, 2, 3]; //arr.length = 3 console.log(arr.length + arr[2]); // arr[2] = 3 0 solved What will the following code regarding arrays print?
You’re very close. Hope this helps. #include <iostream> using namespace std; int main(int argc, char *argv[]) { int numbers[5]; /* Get size of array */ int size = sizeof(numbers)/sizeof(int); int val; for(int i = 0; i < size; i++) { cout << “Enter a number: “; cin >> val; numbers[i] = val; } /* Start … Read more
