The task is to find the length of the longest subsequence in a given array of integers such that all elements of the subsequence are sorted in ascending order. For example, the length of the longest increasing subsequence(LIS) for {15, 27, 14, 38, 26, 55, 46, 65, 85} is 6 and the longest increasing ...

Ionic’s grid system is based on flexbox, a CSS feature supported by all devices that Ionic supports. The grid is composed of three units-grid, rows and columns. Columns will expand to fill their row, and will resize to fit additional columns. ClassWidthwidth-1010%width-2020%width-2525%width-3333.33...

Given a string what is the longest palindromic subsequence(LPS) of it? Let's take a string agbdba. The LPS of this string is abdba of length 5. Remember, since we're looking for subsequence, the characters need not to be continuous in the original string. The longest palindromic substring of the seq...

In order to search for packages in the databse, searching both in packages' names and descriptions: pacman -Ss string1 string2 ... To install a single package or list of packages (including dependencies), issue the following command: sudo pacman -S package_name1 package_name2 ... source

This chapter describes how to set up a Docker Container with Jenkins inside, which is capable of sending Docker commands to the Docker installation (the Docker Daemon) of the Host. Effectively using Docker in Docker. To achieve this, we have to build a custom Docker Image which is based on an arbitr...

Given coins of different denominations and a total, in how many ways can we combine these coins to get the total? Let's say we have coins = {1, 2, 3} and a total = 5, we can get the total in 5 ways: 1 1 1 1 1 1 1 1 2 1 1 3 1 2 2 2 3 The problem is closely related to knapsack problem. The o...

Given coins of different denominations and a total, how many coins do we need to combine to get the total if we use minimum number of coins? Let's say we have coins = {1, 5, 6, 8} and a total = 11, we can get the total using 2 coins which is {5, 6}. This is indeed the minimum number of coins require...

$a1 = array("red","green"); $a2 = array("blue","yellow"); print_r(array_merge($a1,$a2)); /* Array ( [0] => red [1] => green [2] => blue [3] => yellow ) */ Associative array: $a1=array("a"=>"red","b"=&...

The caching problem arises from the limitation of finite space. Lets assume our cache C has k pages. Now we want to process a sequence of m item requests which must have been placed in the cache before they are processed.Of course if m<=k then we just put all elements in the cache and it will wo...

Adding the aurelia-configuration to a cli application sometimes produces a build error. This is caused by a missing dependency so we simply add the dependency to the build bundle. Try the following: npm install deep-extend --save npm install aurelia-configuration --save Now add the followi...

Preface Instead of starting with a formal definition, the goal is to approach these topic via a row of examples, introducing definitions along the way. The remark section Theory will consist of all definitions, theorems and propositions to give you all informations to faster look up specific aspect...

Converting a java.util.Calendar object: Calendar rightNow = Calendar.getInstance(); LocalDate today = LocalDate.fromCalendarFields(rightNow); Converting a java.util.Date object: Date rightNow = new Date(); LocalDate today = LocalDate.fromDateFields(rightNow); Converting a string: String d...

The Proxy :: k -> * type, found in Data.Proxy, is used when you need to give the compiler some type information - eg, to pick a type class instance - which is nonetheless irrelevant at runtime. {-# LANGUAGE PolyKinds #-} data Proxy a = Proxy Functions which use a Proxy typically use Scoped...

Description: mov copies values of bits from source argument to destination argument. Common source/destination are registers, usually the fastest way to manipulate values with[in] CPU. Another important group of source_of/destination_for values is computer memory. Finally some immediate values m...

This is usually used for renaming or shortening long namespace references such referring to components of a library. namespace boost { namespace multiprecision { class Number ... } } namespace Name1 = boost::multiprecision; // Both Type declarations are equivale...

Php arrayiterator allows you to modify and unset the values while iterating over arrays and objects. Example: $array = ['1' => 'apple', '2' => 'banana', '3' => 'cherry']; $arrayObject = new ArrayObject($array); $iterator = $arrayObject->getIterator(); for($iterator; $iterator-...

To declare a single namespace with hierarchy use following example: namespace MyProject\Sub\Level; const CONNECT_OK = 1; class Connection { /* ... */ } function connect() { /* ... */ } The above example creates: constant MyProject\Sub\Level\CONNECT_OK class MyProject\Sub\Level\Connection...

GridView definition on ASPX page As shown below, first column of grid is defined as a checkbox column, which is conditionally cleared as shown in further examples below (the header checkbox is only for selecting/un-selecting all rows on current page, but same can be extended for all on grid easily)...

instanceof requires that the variable is of type any. This code (try it): class Pet { } class Dog extends Pet { bark() { console.log("woof"); } } class Cat extends Pet { purr() { console.log("meow"); } } function example(foo: any) { ...
