A Vector3 structure can be created in several ways. Vector3 is a struct, and as such, will typically need to be instantiated before use. Constructors There are three built in constructors for instantiating a Vector3. ConstructorResultnew Vector3()Creates a Vector3 structure with co-ordinates of...

The Vector3 structure contains some static functions that can provide utility when we wish to apply movement to the Vector3. Lerp and LerpUnclamped The lerp functions provide movement between two co-ordinates based off a provided fraction. Where Lerp will only permit movement between the two co-or...

Setup ActiveMQ Download a ActiveMQ distribution from activemq.apache.org and unpack it somewhere You can start the server immediately, running unsecured on localhost, using the script bin/activemq When it is running, you can access your local server's console on http://localhost:8161/admin/ Co...

Android Apps are written in Java. The Android SDK tools compile the code, data and resource files into an APK (Android package). Generally, one APK file contains all the content of the app. Each app runs on its own virtual machine(VM) so that app can run isolated from other apps. Android system wor...

First of all you should know that you can extend Android.Application class so you can access two important methods related with app lifecycle: OnCreate - Called when the application is starting, before any other application objects have been created (like MainActivity). OnTerminate - This...

Activity lifecycle is quite more complex. As you know Activity is single page in the Android app where user can perform interaction with it. On the diagram below you can see how Android Activity lifecycle looks like: As you can see there is specific flow of Activity lifecycle. In the mobile appl...

As you know you can have one activity but different fragments embedded in it. That is why fragment lifecycle is also important for developers. On the diagram below you can see how Android fragment lifecycle looks like: As described in the official Android documentation you should implement at le...

If you would like to get base project with methods described below you can download Xamarin.Android application template from my GitHub. You can find examples for: Application lifecycle methods Activity lifecycle methods Fragment lifecycle methods https://github.com/Daniel-Krzyczkowski/Xamar...

Consider the Binary Tree: Pre-order traversal(root) is traversing the node then left sub-tree of the node and then the right sub-tree of the node. So the pre-order traversal of above tree will be: 1 2 4 5 3 6 7 In-order traversal(root) is traversing the left sub-tree of the node then the node ...

For example if the given tree is: Level order traversal will be 1 2 3 4 5 6 7 Printing node data level by level. Code: #include<iostream> #include<queue> #include<malloc.h> using namespace std; struct node{ int data; node *left; node *right; }; ...

Glass.Mapper.Sc allows you to move your data from Sitecore and into your code seamlessly using strongly typed objects. The framework allows you to map data on to c# classes and interfaces without any additional mark-up. As the data is mapped to your target objects it is converted to the target type...

// Create a new read-only Set<String> val set = setOf(1, 3, 5) println(set) // prints "[1, 3, 5]"

JdbcTemplate also provides convenient methods to execute batch operations. Batch Insert final ArrayList<Student> list = // Get list of students to insert.. String sql = "insert into student (id, f_name, l_name, age, address) VALUES (?, ?, ?, ?, ?)" jdbcTemplate.batchUpdate(sql, n...

You can pass parameters by Bundle: Bundle myBundle = new Bundle(); myBundle.putString(MY_KEY, myValue); Get the value in onCreateLoader: @Override public Loader<String> onCreateLoader(int id, final Bundle args) { final String myParam = args.getString(MY_KEY); ... }

CIDER function cider-eval-last-sexp can be used to execute the the code while editing the code inside the buffer. This function is by default binded to C-x C-e or C-x C-e. CIDER manual says C-x C-e or C-c C-e will: Evaluate the form preceding point and display the result in the echo area and/or ...

CIDER function cider-insert-last-sexp-in-repl can be used to execute the the code while editing the code inside the buffer and get the output pretty printed in a different buffer. This function is by default binded to C-c C-p. CIDER manual says C-c C-p will Evaluate the form preceding point and ...

Consider the tree: Lowest common ancestor of nodes with value 1 and 4 is 2 Lowest common ancestor of nodes with value 1 and 5 is 3 Lowest common ancestor of nodes with value 2 and 4 is 4 Lowest common ancestor of nodes with value 1 and 2 is 2

For example if the inputs are: Example:1 a) b) Output should be true. Example:2 If the inputs are: a) b) Output should be false. Pseudo code for the same: boolean sameTree(node root1, node root2){ if(root1 == NULL && root2 == NULL) return true; if(root1 == NULL ...
