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: function heapsor...

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); } }

Pigeonhole Sort is a sorting algorithm that is suitable for sorting lists of elements where the number of elements (n) and the number of possible key values (N) are approximately the same. It requires O(n + Range) time where n is number of elements in input array and ‘Range’ is number of possible va...

Radix Sort is lower bound comparison based algorithm. It is a non-comparative integer sorting algorithm that sorts data with integer keys by grouping keys by individual digits which share some significant position and value. Radix sort is a linear time sorting algorithm that sort in O(n+k) time whe...

DBCC commands can show information about database objects. DBCC PROCCACHE Displays information in a table format about the procedure cache. DBCC OUTPUTBUFFER ( session_id [ , request_id ]) Returns the current output buffer in hexadecimal and ASCII format for the specified session_id (and o...

SQL Query optimizer will choose the baes possible plan that he can find for some query. If you can find some plan that works optimally for some query, you can force QO to always use that plan using the following stored procedure: EXEC sp_query_store_unforce_plan @query_id, @plan_id From this poi...

With the 2.x versions of typescript, typings are now available from the npm @types repository. These are automatically resolved by the typescript compiler and are much simpler to use. To install a type definition you simply install it as a dev dependency in your projects package.json e.g. npm i -...

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 ...
