For any operation that accepts an immediate, you can set the other operand to be the identity element of that operation: x = op(x, I). Here are some options: Add or subtract 0 Perform bitwise OR with 0 Perform bitwise AND with all 1s (-1 in 2’s complement) Multiply with or divide by 1 12 … Read more

Looks like an interesting case on what is allowed as a generic parameter type name. This: class DoesSomething<T> : IDoSomething<string> { public void Dispose() { } } and this class DoesSomething<T> : IDoSomething<String> { public void Dispose() { } } is obvious. Here T is used as a generic parameter name. On the other hand … Read more
You have to compare the three condition with AND (in php &&) so if ALL of three numbers are > 0 the if condition is verified. if($qt1 >= 0 && $qt2 >= 0 && $qt3 >= 0){ //your code if all three numbers are >= 0 } solved Check if a number is negative in … Read more

You could use StorageFile.GetThumbnailAsync method to do this. If you want to get more info, please refer to the Scenario2 of official sample.

Your getter/setter of objects in your pool manager should not instantiate or destroy gamobjects, but enable and disable them. That is the purpose of pooling. It makes more sense to EnQueue/deQueue them and activate/deactivate like this. private Queue<GameObject> objPool; private Queue<GameObject> activeObj; //get from pool public GameObject GetObjFromPool(Vector3 newPosition, Quaternion newRotation) { GameObject newObject = … Read more
There’s no built-in method what you’re looking for (merging slices). However, you can use append method like: s.setGrade(append([]int{80}, s.Grade[1:]…)) If you had to update two grade ints then you could have done: s.setGrade(append([]int{80,95}, s.Grade[2:]…)) 1 solved Index slice within Main func when using setGrade()
I don’t think you’re really asking about what Collections.shuffle does in general: I think you’re asking why Collections.shuffle affects the output: You are creating a load of tasks of two kinds: one of them increments a value (“kind 1”); the other increments a value and sometimes prints a message (“kind 2”). These are put into … Read more
constructArray doesn’t actually do anything relevant, set aside leaking memory. Same for printArray. I guess you began to code in c++ not that long ago, the code you’ve written does the following: void constructArray (No *Number, int size) { // allocates enough memory to store n=size pointers to No then constructs them // stores the … Read more
In order for you to successfully extract an array of 5 elements like you tried via “list”, you need to make sure the performAllUpdates function returns an array of 5 elements minimum. For example, the following return statement in the function will work: return array($response1,$response2,$response3,$response4,$response5); But of course $response1 through $response5 need to be replaced … Read more
You are missing some typenames and have the class template Move definition repeated three times. Th below code works: #include <iostream> #include <type_traits> using namespace std; template <typename T> class remove_all_pointers{ public: typedef T type; }; template <typename T> class remove_all_pointers<T*>{ public: typedef typename remove_all_pointers<T>::type type; }; template <typename T> class remove_all_pointers<T* const>{ public: typedef … Read more
Assuming you have string and number in pairs. You can try following logic var abc = [‘S’, ‘L’, ‘M’, 20, 30, 60]; var updated = []; var mid = abc.length/2; for (var i=0; i< mid;i++) { updated.push(abc[i]); updated.push(abc[mid+i]); } console.log(updated); 0 solved How to Invert an array in javascript
