Heap sort is a comparison based sorting technique on binary heap data structure. It is similar to selection sort in which we first find the maximum element and put it at the end of the data structure. Then repeat the same process for the remaining items.
Pseudo code for Heap Sort:

Presumably the simplest way to use compose is with a View only. This allows you to include HTML templates without the need to declare a ViewModel with bindable properties for each of them, making it easier to reuse smaller pieces of HTML.
The BindingContext (ViewModel) of the View will be set to th...
Using compose with a View, ViewModel and Model is an easy way to reuse and combine different Views and ViewModels.
Given the following View and ViewModel (applies to each alternative below):

</template>

There are quite a number situations where one has huge amounts of data and using which he has to classify an object in to one of several known classes. Consider the following situations:

Let's say we have 8 houses. We want to setup telephone lines between these houses. The edge between the houses represent the cost of setting line between two houses.
Our task is to set up lines in such a way that all the houses are connected and the cost of setting up the whole connection is mini...

When run with no arguments, this program starts a TCP socket server that listens for connections to 127.0.0.1 on port 5000. The server handles each connection in a separate thread.
When run with the -c argument, this program connects to the server, reads the client list, and prints it out. The clie...
Consider the following Java classes:
class Foo {
private Bar bar;
public void foo() {
bar.baz();
}
}
As can be seen, the class Foo needs to call the method baz on an instance of another class Bar for its method foo to work successfully. Bar is said to be a dependency for Foo sin...
The same examples as shown above with XML configuration can be re-written with Java configuration as follows.
Constructor injection
@Configuration
class AppConfig {
@Bean
public Bar bar() { return new Bar(); }
@Bean
public Foo foo() { return new Foo(bar()); }
}
Property in...
Dependencies can be autowired when using the component scan feature of the Spring framework. For autowiring to work, the following XML configuration must be made:
<context:annotation-config/>
<context:component-scan base-package="[base package]"/>
where, base-package is th...
Constructor injection through Java configuration can also utilize autowiring, such as:
@Configuration
class AppConfig {
@Bean
public Bar bar() { return new Bar(); }
@Bean
public Foo foo(Bar bar) { return new Foo(bar); }
}
