Assign views randomly using an array - react native

Assign views randomly using an array - react native



I'm trying to come up with a way of randomly inserting views into a flexbox grid I've made in my app. The app looks like this



enter image description here



I have an array which will have a maximum of 6 elements, however these can change.
I want to insert these elements into the grid at random, however it's proving to be more difficult than I expected.



I grab the array asynchronously, so it needs to update on the fly.



Can anyone recommend any way of doing this? I'd post the code I've tried but it's pretty useless up to now.






You think your code is useless but maybe it is not, so just share it.

You could randomly select an index of the array, populate the grid, and then pop that index from the array? Really need more info. Can you use a view more than once? What triggers the grid to get populated? I've used this function to randomly select from an array: const randomArrayIndex = (arr) => arr[Math.floor(Math.random() * arr.length)]; Not sure if this will point you in the right direction.

PHP code is not being executed, instead code shows on the page

266 58 I'm trying to execute some PHP code on a project (using Dreamweaver) but the code isn't being run. When I check the source code, the PHP code appears as HTML tags (I can see it in the source code). Apache is running properly (I'm working with XAMPP), the PHP pages are being opened properly but the PHP code isn't being executed. Does someone have a suggestion about what is happening?

Cardinality of the set of algorithms

Image
15 3 $begingroup$ Someone in a discussion brought up that (he reckons) there can be at least continuum number of strategies to approach a specific problem. The specific problem was trading strategies (not algorithms but strategies) but I think thats beside the point for my question. This got me thinking about the cardinality of the set of algorithms. I have been searching around a bit but have come up with nothing. I've been thinking that, since turing machines operate with a finite set of alphabet and the tape has to be indexable thus countable, it's impossible to have uncountable number of algorithms. My set theory is admittedly rusty so I am not certain at all my reasoning is valid and I probably wouldn't be able to prove it, but it's an interesting thought. What is the cardinality of the set of algorithms? algorithms turing-machines combinatorics share | cite | improve this question edited Aug 28 '18 at 13:59 Raphael ♦ 57.8k 24...
