public class BucketSort { public static void SortBucket(ref int[] input) { int minValue = input[0]; int maxValue = input[0]; int k = 0; for (int i = input.Length - 1; i >= 1; i--) { if (input[i] > maxValue) maxValue = input...

The .map function accepts an array and an iteratee function, the iteratee produces a transformed copy of each array object. The iteratee function provides 3 arguments item - The current iterated object i - The index of the iterated object list - A reference to the original array/list The ne...

Install a Common Lisp implementation on the server. (E.g. sbcl, clisp, etc...) Install quicklisp on the server. Load SWANK with (ql:quickload :swank) Start the server with (swank:create-server). The default port is 4005. [On your local machine] Create a SSH tunnel with ssh -L4005:127.0.0.1:400...

The module "struct" provides facility to pack python objects as contiguous chunk of bytes or dissemble a chunk of bytes to python structures. The pack function takes a format string and one or more arguments, and returns a binary string. This looks very much like you are formatting a stri...

for ([declaration-or-expression]; [expression2]; [expression3]) { /* body of the loop */ } In a for loop, the loop condition has three expressions, all optional. The first expression, declaration-or-expression, initializes the loop. It is executed exactly once at the beginning of the lo...

A loop is said to be an infinite loop if the control enters but never leaves the body of the loop. This happens when the test condition of the loop never evaluates to false. Example: C99 for (int i = 0; i >= 0; ) { /* body of the loop where i is not changed*/ } In the above example...

Player playerToHide; Player playerToNotSee; playerToNotSee.hide(playerToHide); //playerToHide will no longer be seen by playerToNotSee. If player is already hidden, nothing happens

Player toUnhide; Player toSeeAgain toSeeAgain.show(toUnhide); //Player toSeeAgain will now see Player toUnhide again. If player is already visible, nothing happens.

Player playerToCheck; Player playerSeeing; boolean isVisible = playerSeeing.canSee(playerToCheck); //isVisible returns true if playerSeeing can see playerToCheck and false otherwhise

This can be done by using the event EntityTargetEvent Entities won't target the player if you cancel the event: @EventHandler public void onEntityTarget(EntityTargetEvent e) { Entity target = e.getEntity(); if(target instanceof Player) { Player playerTargetted = (Player) target...

Log in to the AWS Management Console and navigate to AWS Lambda. Click create new function then you will see this window. Select Runtime environment but blueprint (sample code) only for node.js and python There are two example conation for alexa skills kit. You can filter those thing. By s...

Type declaration: CREATE OR REPLACE TYPE base_type AS OBJECT ( base_id INTEGER, base_attr VARCHAR2(400), null_attr INTEGER, -- Present only to demonstrate non-default constructors CONSTRUCTOR FUNCTION base_type ( i_base_id INTEGER, i_base_attr VARCHAR2 ...

This example shows how to populate report with data returned by a data view delegate. During the exercise, we will develop an inquiry screen showing list of Sales Orders between two dates. Data view delegate will be used to populate Sales Order information. Prerequisites: We start with declara...

The let expressions in scheme are in fact macros. They can be expressed with lambdas. A simple let might look like this: (let ((x 1) (y 2)) (+ x y)) It will return 3 as the value of the last expression of the let body is returned. As you can see, a let-expression is actually executing somethi...

You can also make a switch statement switch based on the class of the thing you're switching on. An example where this is useful is in prepareForSegue. I used to switch based on the segue identifier, but that's fragile. if you change your storyboard later and rename the segue identifier, it breaks ...

Parsing files into STL containers istream_iterators are very useful for reading sequences of numbers or other parsable data into STL containers without explicit loops in the code. Using explicit container size: std::vector<int> v(100); std::copy(std::istream_iterator<int>(ifs), std::...

If a function returns a std::vector type, and it is exposed to Python directly like std::vector<float> secondMethod() { return std::vector<float>(); } BOOST_PYTHON_MODULE(CppProject) { boost::python::def("getEmptyVec", secondMethod); } then when the functions...
