It could be some simple or complex calculation, I don’t know ‘-‘. I just know that I couldn’t solve. For example: [code]$list = [ ‘first’ => [ ‘a’, ‘b’, ‘c’, ‘d’ ], ‘second’ => [ ‘e’, ‘f’ ], ‘third’ => [ ‘g’, ‘h’ ] ]; $allCombinations = [ 0 => ‘first=a,second=e,third=g’, 1 => ‘first=a,second=e,third=h’, 2 => ‘first=a,second=f,third=g’, ……

In this post, we will see how to resolve Dereferenced Pointer to Vector Element in Object doesn’t Update Value Question: I am trying to make a toy Entity Component System to improve on my C++ skills. To do so, I have an ECS_Manager Class, which uses templates to have multiple storage classes for each data type I’d like to use as a component. Each component is just a struct with an int and whatever else data I’d like. In the example, it contains a Vector2D object. Nothing special. As a starting point, internally the storage class for each component type…

In this post, we will see how to resolve Relation between height and depth of not complete binary tree Question: “Let H be the height of the tree. If the heap is not a complete binary tree (because the bottom level is not full), then the nodes at a given depth don’t all have the same height. Eg., although all the nodes with depth H have height 0, the nodes with depth H-1 may have either height 0 or 1” Found this explanation when searching for the explanation of statement –“max node with given height h in N-element heap =…
