you can use an expression bodied method. static double Stirling(long n) => Math.Sqrt((2 * n + 1.0 / 3.0) * Math.PI) * Math.Pow(n, n) / Math.Exp(n); This is only possible when the method executes a single statement, and in this case, we get rid of the return statement. or you can use a Func delegate … Read more
A default macOS installation will include something that pretends to be gcc but that’s just a legacy concern so that portable programs will properly detect a compiler when you do a source install with the usual ./configure && make && make install or use a package manager like Homebrew. Xcode used to use gcc as … Read more
I think you’ve said why in your question, but just for clarity: Double(double) works just fine if you pass it a float, so there’s no need for Double(float). This is because in a constructor invocation (JLS§5.3), a widening primitive conversion (JLS§5.1.2) is allowed. float to double is a widening primitive conversion. But Float(float) would not … Read more

You can use \DOMDocument->loadHTML(); Ex: <?php $doc = new \DomDocument(); $doc->loadHTML(‘<div class=”whatever”> Title </div>’); View examples here: http://docs.php.net/manual/en/domdocument.loadhtml.php This is assuming that your source is available to php. It would probably be more pragmatic to extract the value with javascript in the client and send it with the page request. If your app is well … Read more

Actually figured it out – was very simple. NewDataFrame <- data.frame(colnames(Original)) solved R: create new dataframe rows are columns from another dataframe
EDIT: Sorry, misread your question. I thought you only wanted to keep these values. Changed my code accordingly. list1 = [“13:00″,”13:10″,”13:20″,”13:30″,”13:40”] range_start = “13:10” range_end = “13:30” You can use list comprehension with the range condition: list1 = [x for x in list1 if not(range_start<=x<=range_end)] print(list1) You could also use filter on your list: list1=list(filter(lambda … Read more

How about using the basic base 10 to any base conversion, modified for custom digits: func numberToCustomRadix(_ number: Int, alphabet: String) -> String { let base = alphabet.count var number = number var result = “” repeat { let idx = alphabet.index(alphabet.startIndex, offsetBy: number % base) result = [alphabet[idx]] + result number /= base } … Read more
The problem you describe is actually a very difficult problem in general, since it is related to the knapsack problem. But it is only hard if you allow very large amounts of money on the card and very many different prices. For your real world problem with very few different prices you can solve this … Read more
