[Solved] Align item center and right [closed]

by

Basically, you’d need to use absolute positioning to take the buttons (I’ve wrapped them here for simplicity) out of the flow so the title can center. .parent { text-align: center; position: relative; border: 1px solid green; } h1 { display: inline-block; } button { display: inline-block; } .wrap { position: absolute; top: 50%; transform: translateY(-50%); … Read more

[Solved] I have around 1000 different activities in my Android App. How can I jump to a random activity?

by

Although this is terrible, I’ll still show a possible way to do this. But just remember, this is TERRIBLE. You can store all the activity classes in an ArrayList. ArrayList<Class<Activity>> activities = new ArrayList<> (); And then you add all the activities into the ArrayList. Yeah, I know, this part is tedious. For example, activities.add … Read more

We need to skew the perspective as well to get the real effect. UITextView *textView = [[UITextView alloc] initWithFrame:self.view.bounds]; [textView … Read more

[Solved] Why does my program crash if I don’t give command line arguments to it? [closed]

by

It crashes because you are accessing argv[1] which would hold a command line argument (other than the program’s name) if there was one. You should check whether argc is greater than 1. Why greater than 1? Because the first command line argument is the name of the program itself. So argc is always greater than … Read more

[Solved] Write this Scala Matrix multiplication in Haskell [duplicate]

by

It’ll be perfectly safe with a smart constructor and stored dimensions. Of course there are no natural implementations for the operations signum and fromIntegral (or maybe a diagonal matrix would be fine for the latter). module Matrix (Matrix(),matrix,matrixTranspose) where import Data.List (transpose) data Matrix a = Matrix {matrixN :: Int, matrixM :: Int, matrixElems :: … Read more
