I would like a review for this simple recursive algorithm which returns the largest int in an array of integers. I would like feedback on the transfer of state via the third parameter specifically. Please also note 2 things:

the following question was closed as off topic
Count maximum number of thieves that can be caught
the code seems complete to me and the question is complete and clear. moreover, I have started to code an answer.
I created an interface (IFXMLComponent) that can be added to a FXML controller class.
The FXML controller class that implements this interface will be associated with an FXML file.
The interface both support custom FXML components, in that case the FXML controller class extends a JavaFX node (e...
Is it a good or bad practice to use closures for asserting the method was called in such a way?
The method set a shim and return an Action wich both capture local mutable variable:

I recently faced this question in an online programming contest:
There is a N * N grid.
1) Each cell of the grid can have either a police denoted by P or a thief denoted by T.
2) A police can catch a thief only if they are in a same row.
3) A police can catch only one thief.
4) A police cannot c...
Steps to reproduce:
Try to edit Count maximum number of thieves that can be caught
Expected results
An error message, if applicable, should appear in a red box
Actual result
An error message appears on a blank page
There is a pending suggested edit in the queue. Try again in a few minutes.

Usage is pretty straightforward
You can encrypt from a file to another file

I have a function that I wrote a while ago in PHP called ifempty, which I could pass an infinite(ish) amount of values and it would return the first one that wasn't purely white space or empty, like ifempty('', null, '\n\n\n \t', 'test') would return 'test'; That one works awesome. But then I n...

We would like to perform n-fold non-stratified cross-validation on a model, say an lm or glm.
We have a list of quality metrics we would like to evaluate, which we wrap in a function:
