One option to your expected output is to create a indexed array with the associative array below it. This will create this kind of array: array(4) { [0]=> array(1) { [203]=> int(1) } [1]=> array(1) { [204]=> int(2) } [2]=> array(1) { [203]=> int(2) } [3]=> array(1) { [205]=> int(1) } } This is not … Read more
Position of the first circle is described as x1 = x1_0 + vx1 * t y1 = y1_0 + vy1 * t where x10 is initial x-coordinate, vx1 is x-component of velocity vector, t is time. Make similar expression for the second circle center, build expression for squared distance and find time when squared distance … Read more
{} is just an empty Json object, and it will decode fine to your Operandsstruct, as the struct is not required to have anything in the Operands array. You need to validate that yourself, e.g. err := json.NewDecoder(req.Body).Decode(&operands) if err != nil || len(operands.Values) == 0{ solved Golang not producing error when decoding “{}” body … Read more
You can’t apply the ++ operator to a string, but you can implement this logic yourself. I’d go over the string from its end and handle each character individually until I hit a character that can just be incremented simply: public static String increment(String s) { StringBuilder sb = new StringBuilder(s); boolean done = false; … Read more
One solution is to use the sync modifier along with computed getters and setters: Parent Component <template> … <PaymentMethod :method.sync=”method” :term.sync=”term”/> … <b-btn class=”float-right” variant=”primary” @click=”add”> OK </b-btn> … </template> <script> export default { data () { return { method: null, term: null } }, … } </script> Child Component <template> … <b-form-select v-model=”_method” :options=”methodOptions” … Read more

What’s Wrong You’re trying to use a “variable variable” by building a variable name from two pieces, split and $i. This is not usually the best way to do things, and you’re doing it incorrectly. $split($i) doesn’t mean “the variable named ‘split and the value of $i.’” It means, “take a variable named $split, treat … Read more
x |= -(x == 0); x |= -!x; x = x ? x : 0xFFFFFFFF; if (x == 0) x = 0xFFFFFFFF; … Benchmark and choose what’s appropriate for you 4 solved Bithack for: if x is 0, then x should be -1, else x should be untouched
It would help to see how you push items onto the stack. If you’re really calling pop without a push first, well, then it’s not supposed to do anything, is it? This bit makes me nervous: Node *aux,*prev; prev = *stack; aux = prev->next; if(aux == NULL) { free(prev); return; } You set prev to … Read more
VS doesn’t create directories for you. The view you see is “filters”. Organization on the disk is flat unless you tell it otherwise, and it’s moderately painful. The project on github will reflect the directory structure, not VS’s “filters”. 1 solved Visual Studio C++ structure on Github
You have to create a table in your view like this: <table class=”game-board” ng-controller=”GameBoardController as gameBoard”> <tr ng-repeat=”row in boardArr”> <td ng-repeat=”col in row”>{{ col }}</td> </tr> </table> So ng-repeat will iterate over boardArr and then you can display the values in different cells like I did above. You don’t have to access the value … Read more
Here’s a way with nested loops (semi-pseudocode): int x ; //check if x is a multiple of any two factors < x for (int i1 = 2 ; i1 < x ; i1++) { for (int i2 = i1 ; i2 < x ; i2++) { prod = i1 * i2 ; if (prod > … Read more
For Python you could go with Frontera by Scrapinghub https://github.com/scrapinghub/frontera https://github.com/scrapinghub/frontera/blob/distributed/docs/source/topics/distributed-architecture.rst They’re the same guys that make Scrapy. There’s also Apache Nutch which is a much older project. http://nutch.apache.org/ 1 solved How to build a powerful crawler like google’s? [closed]

One way to do it would be to have a new property on your myClass public class myClass { private string _setString; public string setString { get { return _setString; } set { AuditTrail += value; _setString = value; } } public string AuditTrail{get;set;} } Then in your main method you’d put: Console.WriteLine(AuditTrail); 0 solved … Read more
