An example of implementation UITableView which allows to detect if cell has been tapped single or double time. override func viewDidLoad() { viewDidLoad() let doubleTapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(handleDoubleTap(sender:))) doubleTa...

Create new instance of UISegmentedControl filled with 3 items (segments): let mySegmentedControl = UISegmentedControl (items: ["One", "Two", "Three"]) Setup frame; mySegmentedControl.frame = CGRect(x: 0.0, y: 0.0, width: 300, height: 50) Make default s...

For those who haven't played with these two designs, the scope of lazy and eager is within a specific Session of SessionFactory. Eager loads everything instantly, means there is no need to call anything for fetching it. But lazy fetch usually demands some action to retrieve mapped collection/object....

To create a background with a gradient you can use the CAGradientLayer class: Swift 3.1: func createGradient() { let caLayer = CAGradientLayer() caLayer.colors = [UIColor.white, UIColor.green, UIColor.blue] caLayer.locations = [0, 0.5, 1] caLayer.bounds = self.bounds self...

To add a custom image for the thumb of the slider, simply call the setThumbImage method with your custom image: Swift 3.1: let slider = UISlider() let thumbImage = UIImage slider.setThumbImage(thumbImage, for: .normal)

multiply-square-matrix-parallel(A, B) n = A.lines C = Matrix(n,n) //create a new matrix n*n parallel for i = 1 to n parallel for j = 1 to n C[i][j] = 0 pour k = 1 to n C[i][j] = C[i][j] + A[i][k]*B[k][j] return C

matrix-vector(A,x) n = A.lines y = Vector(n) //create a new vector of length n parallel for i = 1 to n y[i] = 0 parallel for i = 1 to n for j = 1 to n y[i] = y[i] + A[i][j]*x[j] return y

A is an array and p and q indexes of the array such as you gonna sort the sub-array A[p..r]. B is a sub-array which will be populated by the sort. A call to p-merge-sort(A,p,r,B,s) sorts elements from A[p..r] and put them in B[s..s+r-p]. p-merge-sort(A,p,r,B,s) n = r-p+1 if n==1 ...

Suppose we have a simple class with validation annotations public class UserDTO { @NotEmpty private String name; @Min(18) private int age; //getters/setters } A controller to check the UserDTO validity. @RestController public class ValidationController { @Reque...

In following example we will create table movies with AWS Ruby SDK v2. Here, each Movie as one unique Partition Key as id, and Range Key year. Apart from this we want to be able to query movies with their name, hence we will create a Global Secondary Index (GSI) name-year-index with name as Hash Ke...

Q-learning is a variant of model-free reinforcement learning. In Q-learning we want the agent to estimate how good a (state, action) pair is so that it can choose good actions in each state. This is done by approximating an action-value function (Q) that fits in equation below: Where s and a are ...
