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...

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...

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 ...

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...
