For example I have 4 numbers: 10, 3, 2, 1
Then the question is "How to make 4 numbers above to 24 ?"
The answer is (10-2) * (3 * 1) = (8 * 3) = 24
What is the name of the algorithm in the programming language? to predict the operator (-, +, /, *) in the case above
These fit within the broad class of constraint satisfaction problems - essentially you can easily test a solution, but you need to search to find one. There are several algorithms for dealing with various formulations of constraint satisfaction problems.

Everyone knows leet code website has many tags like:
array,linked list,...etc
if you want do some practice about array or tree you can just go
https://leetcode.com/tag/array/
https://leetcode.com/tag/tree/
so my question is diretly simple
How many kinds of tags are there in leet code?
Can anyone give me a link that can see all tags in leetcode?
In Leetcode problem page, you can choose the tag for problems. Leetcode Link

I am trying to train tenserflow U-net, for multi-class segmentation of heart. I have 3 labels and the prediction has 3 probability maps (one probability map for every label). I trained with momentum optimizer which is also the default optimizer of the network. In the very beginning iterations, the probability mapping of label 1 and label 2 are different but after some iterations (or epochs) the probability map of label 1 and label 2 become exactly like each other and technically I have a binary label segmentation. I have seen other networks that have similar architecture like U-net and they have trained on the multi-class dataset. I want to find some multiclass segmentation examples with U-net but all examples are binary.

Is there any probabilistic algorithm for calculating set cardinality taking into account that must support deleting elements from set? I've been using HyperLogLogs for calculating cardinalities of some sets and their unions but when necessity of deleting elements from set emerged my current solution became unappropriate. Maybe there are some researches or papers related to this topic you could advise.

I'm looking for an algorithm that can tell me where are the eye(s) looking at on a photo/webcam realtime feed.
I've already searched a lot but I don't want to start with a lot of complexity right now.
It's just for fun. My idea it's to have some method that receives an image and returns a coordinate with the place that the user is looking (on the computer screen).
