There are two classes of methods for solving Linear Equations: Direct Methods: Common characteristics of direct methods are that they transform the original equation into equivalent equations that can be solved more easily, means we get solve directly from an equation. Iterative Method: It...

An equation of the type f(x)=0 is either algebraic or transcendental. These types of equations can be solved by using two types of methods- Direct Method: This method gives the exact value of all the roots directly in a finite number of steps. Indirect or Iterative Method: Iterative method...

Nesting controllers chains the $scope as well. Changing a $scope variable in the nested controller changes the same $scope variable in the parent controller. .controller('parentController', function ($scope) { $scope.parentVariable = "I'm the parent"; }); .controller('childContro...

An Odd-Even Sort or brick sort is a simple sorting algorithm, which is developed for use on parallel processors with local interconnection. It works by comparing all odd/even indexed pairs of adjacent elements in the list and, if a pair is in the wrong order the elements are switched. The next step ...

To connect to a server we must use SSH on the client as follows, # ssh -p port user@server-address port - The listening ssh port of the server (default port 22). user - Must be an existing user on the server with SSH privileges. server address - The IP/Domain of the server. For a real wor...

You could describe variable affectation in different ways. Typed int a = 1 int a := 1 let int a = 1 int a <- 1 No type a = 1 a := 1 let a = 1 a <- 1

As long as the function name, return statement and parameters are clear, you're fine. def incr n return n + 1 or let incr(n) = n + 1 or function incr (n) return n + 1 are all quite clear, so you may use them. Try not to be ambiguous with a variable affectation

An example implementation of BubbleSort in C++: void bubbleSort(vector<int>numbers) { for(int i = numbers.size() - 1; i >= 0; i--) { for(int j = 1; j <= i; j++) { if(numbers[j-1] > numbers[j]) { swap(numbers[j-1],numbers(...

public class QuickSort { private static int Partition(int[] input, int low, int high) { var pivot = input[high]; var i = low - 1; for (var j = low; j <= high - 1; j++) { if (input[j] <= pivot) { i++; ...

In C, all arguments are passed to functions by value, including structs. For small structs, this is a good thing as it means there is no overhead from accessing the data through a pointer. However, it also makes it very easy to accidentally pass a huge struct resulting in poor performance, particula...
