Java does not allow you to use super as a value. You cannot return it. And you don’t need to return it, because you can reference the object with this. In Java, an instance of class is represented by one object. The superclass is not represented by a separate object. Classes support inheritance of implementation … Read more
It is 2^n because for each job it is either take it or not take it (0,1). In other words, there are two possibilities for each job. For n jobs it is 2^n. n! Is total of permutations for n jobs, it is used when you have taken n jobs but you want to know … Read more

Changing a const-value yields undefined behaviour, and the “mysterious” output is just such undefined behaviour. It is actually needless to investigate on why a behaviour in the world of undefined behaviour is as it is then. But in your case it is probably not using a as you declare it as const, so the compiler … Read more
Here is a pager control that I created to drop into the PagerTemplate of a GridView. It’s not the most complicated stuff, but it shows how a pager control can ‘see’ the grid that it belongs to and render a dropdown to jump to a specific page.

This with g++ compiles, and I don’t think there’s any UB struct Va { Va(struct Foo&, int) {} }; int operator++(const Va&, int) { return 42; } struct Foo { Va va; Foo(Foo &afoo) : va(afoo,va++) {} }; to be specific operator++ is not doing anything with the not-yet-initialized va data member.

First of all, in general, var <- expr evaluates the R expression expr and assigns the result to the variable var. If the statement occurs inside a function, then var becomes a function-local variable, otherwise, it becomes a global variable. c(0,0,0,1,0,1,0,1,1,1,1,0) Combines 12 double literals into a double vector in the order given. matrix(c(0,0,0,1,0,1,0,1,1,1,1,0),4,3, byrow=T … Read more
