QUESTION
thank you in advance for taking the time to read. I've been with a project on Android using Java for weeks. But I have had this problem for days, I tried many things but nothing worked.
What happens is that the "main" button (black color) that expands the other buttons is; scrolls. Before and after expanding the other buttons.
Ideally, it should stay fixed in place before and after pressing. And that the other white buttons do scroll below the black button.
I attach the complete XML and screenshots.
We open the application and it will look like this:

Then we scroll and ideally nothing happens, but the main button is hidden behind the text box.

We press the main button and as it should be, the other buttons expand.

But we scroll and the buttons instead of getting under the black button, they scrooll all the buttons including the black one.

My scenario is the following:
I have a very big string. I want to convert it into an array where every element is a word. Then in every recursive call I do to my method, I wanna take 50 elements from my words array. For example, in the first call I want to take from 0 to 50, then in the next I want from 50 to 100, etc.
My problem comes when checking if my start and end range for the array is out of bounds or not.
My code is as follows:
...ANSWER
Answered 2019-Apr-23 at 15:39First of all, i would start by creating the array and then split it recursively.
You can easily do it with the array methods shift
or pop
depending on which direction you want to go.
I would probably do something like this:

I'm trying to create a datatable that can be filtered by a data range. It's working basically everything, except for that it throws an exception when trying to update the table after changing the date fields. Here's my code:
tablas.js:
...ANSWER
Answered 2019-Feb-11 at 19:30tablaTransacciones is a JQuery object, not the reference to the DataTables object. So "draw" probably does not exist. When you establish the datatable, capture the result. For example

QUESTION
I'm using a Map with eligible words for a hangman game I'm developing. The Integer in the Map stores the times a word has been chosen, so in the beginning the Map looks like this:
...ANSWER
Answered 2018-May-24 at 09:05I won't provide exact code, but basic idea.
Iterate over
wordList.values()
to find the maximum weightM
and sum of weightsS
.Now let each word
w
have likelihood (like probability, but they don't have to sum to 1) to be chosenM + 1 - wordList.get(w)
, so a word with weight1
isM
times more likely to be chosen than a word with weightM
.The sum of likelihoods will be
(M + 1) * wordList.size() - S
(that's why we needS
). Pick a random numberR
between 0 and this sum.Iterate over
wordList.entrySet()
, summing likelihoods as you go. When the sum passesR
, that's the word you want.
