Just to illustrate my comment, here is how you could rewrite your current filter using BETWEEN. I am going to not assume that there are any rules about the values in [from] and [to], either could be less than the other, or they could be equal. If there were any such rules, then possibly this … Read more

You should take into account that nodejs often uses asyncronous calls, and this is the case with your code too. fs.readFile(‘index.html’, (err,html)=>{ if(err){ throw err; } console.log(html); // html works here }); console.log(html); // html is undefined here This should work fs.readFile(‘index.html’, (err,html)=>{ if(err){ throw err; } var server = http.createServer((req,res)=>{ res.statusCode = 200; res.setHeader(‘Content-type’,’text/plain’); … Read more
For a point p(i,j), it’s position in a matrix is equal to i*width+j where width is the width of the matrix. Hence the number of cells between two elemets is abs((i1*width+j1) – (i2*width+j2)). 1 solved How do i know number of cells between two points in array?
If you want to display the content present in your URL after we hit your URL in browser, we can do the following let url = NSURL(string: “http://atakaractakip.co.nf/atakdeneme.txt”)! let data = NSData(contentsOfURL: url) if data != nil { if let content = String(data: data!, encoding: NSUTF8StringEncoding) { //It will display Onay AKPINAR as this is … Read more
The variable used is a duplicated name. In main the local used is accessed. But in checkData the global instance is used, but causes an error since you are dereferencing a NULL pointer (static variables are initialised to 0). solved C – can’t access global variable within user functions
Introduction When programming in C, it is important to understand the scope of variables. Global variables are variables that are accessible from any part of the program, while local variables are only accessible within the function they are declared in. Unfortunately, it is not always possible to access global variables within user functions. This can … Read more
For this to work, you would have to sort your coins in descending order, or use reversed(coinList) instead of coinList in the first for loop and vice versa in the second if you would like to sort them forwards: total = 250 value = 0 coins = [] coinList = [100, 100, 20, 20, 20, … Read more
Option 1 You can create a single JS object containing all your data (your form data and your hierarchical array). Afterwards, you can send that using jQuery .ajax() method or .post() method.

You have non-unique ID’s for elements – jQuery will not work. Change ID to class. Also remove any reference to event (since there is no such thing on DOM ready). I have converted your JS code to actual jQuery: $(document).ready(function() { $(‘.numberofdaysperchosenfrequency’).each(hideDays); $(‘.numberofdaysperchosenfrequency’).on(‘change’, hideDays); }); function hideDays() { let parent = $(this).parent(); parent.find(‘.daycol’).show(); parent .find(`.daycol:not([data-id=”${$(this).val()}”])`) … Read more
We can try data.table. Convert the ‘data.frame’ to ‘data.table’ (setDT(df2), grouped by ‘RouteId’, if any of the run-length-type id of the logical vector (StopType==’Load’) is greater than 2, we get the Subset of Data.table (.SD). This will give the rows with ‘RouteId’ 103. library(data.table) setDT(df2)[,if(any(rleid(StopType==’Load’) >2)) .SD ,.(RouteId)] # RouteId StopOrder StopType #1: 103 1 … Read more
