Deque: This would be a decent choice, since you can add/remove from both the front/end of the line in O(1) time, and the number of patients can be kept track of with an integer variable, so getting the size of the line would be O(1). You can also ensure a max capacity of N by … Read more
some fundamental coding errors needs to be addressed here along with logical flaw. before we proceed lets format to 4 spaces int main() { /* Lets simplify these two statements */ // char ce[] = {“ceil”}; // char fl[] = {“floor”}; char *ce = “ceil”; char *fl = “floor”; /* format this into one line … Read more
Your problem is that you have nested objects and you want to access them via reflection. That is not working! If your Student would only have one exam, you would need to change the propertyNames to this: String[] propertyNames = { “name”, “groupNumber”, “exam.name”, “exam.mark” }; and the definition of the data provider to this: … Read more
Either LINQ: List<Guid> guids = guidStrings.Select(Guid.Parse).ToList(); or List.ConvertAll which is a little bit more efficient because it knows the size: List<Guid> guids = guidStrings.ConvertAll(Guid.Parse); 0 solved Convert a Collection of Strings into Collection of GUID
You declared the constructor of player as Player(string name, int points);. If you define a function with two parameters you have to use both. Create your object with Player player1 = Player(“Matti”, 0); If you still want to call it with just one parameter you have to set a default value like this. class Player … Read more
Your DrowRanger method is calling itself infinitely. This is almost always the cause of a StackOverflowException. This line: return DrowRanger(); Calls the DrowRanger method, but since you’re inside the DrowRanger method it just keeps calling itself infinitely. I think you meant to return the local object: return DrowRanger; In general, it is a bad idea … Read more
athing.something means “Get the property called something from athing“. If a property doesn’t exist, then it has the value undefined. Your newly created string doesn’t have an abdc property. You can’t compare it to Snippet 1 because you are dealing with a property, not a variable. You can compare it to Snippet 2, which complains … Read more
If you need sequential activity, you can call one task and then another. The simple solution in your case is something like this. ExecutorService exec = Executors.newFixedThreadPool(2); exec.execute(new Runnable() { public void run() { userProvisioner1.run(); userProvisioner2.run(); } }); exec.execute(new Runnable() { public void run() { userProvisioner3.run(); userProvisioner4.run(); } }); exec.shutdown(); exec.awaitTermination(); solved Running Multiple Thread … Read more
Creating some data to work with: tim <- data.frame(2616, 2617, 2388) colnames(tim) <- c(“Jun”, “Jul”, “Aug”) This is our data tim: Jun Jul Aug 1 2616 2617 2388 You can use the melt function and then select only the column you wish to keep. The following code: library(dplyr) library(reshape2) melt(tim, value.name = “Month”) %>% select(Month) … Read more
Here using Date alone causes the problem so Write it as: html += “<td class=”” + className + “”><a href=”#” data-toggle=”modal” data-target=”#tourRequModal” onclick=’dateSel(\”” + new Date().toString() + “\”,” + priceArr[i] + “)’>” + i + priceText + “</a></td>”; solved OnClick function – Uncaught SyntaxError: Invalid or unexpected token
The x += x doubles x every time the innermost statement is executed. The inner loop is executed 1 + 2 + 3 + 4 = 4 * (4 + 1) / 2 = 10 times. Thus, the result must be 2^10 = 1024. For general n, it should be something like 2^((n + 1) … Read more
I’ve created an example below that I think you can work from. The values from the radio I don’t think get updated until you submit, instead I’ve captured the results in the onclick. You can now add back you CSS styling etc. Hope that helps. var results = {}; function updateResult() { var r = … Read more
Any control structure (if, for, while, etc.) without braces applies only to the next statement. The second example is equivalent to the following: for (int i = 0; i < 10; i++) { continue; } cout << i << endl; Note that it’s often considered bad style to have control structures without braces, because people … Read more
TL;DR It is completely possible to have a language without pointers. Actually, it is possible to write a C program where you store addresses in regular integer variables and then cast them to pointers. Calling pointers, and also the general concept of types, syntactic sugar is to stretch it a bit, but it’s not completely … Read more
As the standard says: Internally, the elements in a map are always sorted by its key following a specific strict weak ordering criterion indicated by its internal comparison object (of type Compare). So, elements are sorted automatically as you insert them to the map. solved An unexpected sorting of const map
