Returns elements from the given collection until the specified condition is true. If the first element itself doesn't satisfy the condition then returns an empty collection. Signature of TakeWhile(): Public static IEnumerable <TSource> TakeWhile<TSource>(this IEnumerable <TSource&gt...

Skips elements based on a condition until an element does not satisfy the condition. If the first element itself doesn't satisfy the condition, it then skips 0 elements and returns all the elements in the sequence. Signature of SkipWhile(): Public static IEnumerable <TSource> SkipWhile<TS...

Algorithm This algorithm is a two step process.First we create a auxiliary array lps[] and then use this array for searching the pattern. Preprocessing : We pre-process the pattern and create an auxiliary array lps[] which is used to skip characters while matching. Here lps[] indicates longes...

Check environment variable value e.g. echo %JAVA_HOME% C:\Program Files\Java\jdk1.7.0_51

The vertex shader only accepts the texture coordinates as a vertex attribute and forwards the coordinates to the fragment shader. By default, it will also guarantee that the fragment will receive the properly interpolated coordinate based on its position in a triangle: layout (location = 0) in vec3...

(let [xf (comp (map inc) (filter even?))] (transduce xf + [1 2 3 4 5 6 7 8 9 10])) ;; => 30 This example creates a transducer assigned to the local xf and uses transduce to apply it to some data. The transducer add's one to each of it's inputs and only returns the ...

(def xf (filter keyword?)) Apply to a collection, returning a sequence: (sequence xf [:a 1 2 :b :c]) ;; => (:a :b :c) Apply to a collection, reducing the resulting collection with another function: (transduce xf str [:a 1 2 :b :c]) ;; => ":a:b:c" Apply to a collection, and...

If you call plt.legend() or ax.legend() more than once, the first legend is removed and a new one is drawn. According the official documentation: This has been done so that it is possible to call legend() repeatedly to update the legend to the latest handles on the Axes Fear not, though: It ...

In cases where you need a common portion of the route for all routes within a controller, RoutePrefix attribute is used. In the below example, api/students part of the code is common and so we can define RoutePrefix and avoid using it repeatedly. [RoutePrefix("api/students")] public cla...

In this example I will show you how to make a basic lexer which will create the tokens for a integer variable declaration in python. What does the lexical analyser do? The purpose of a lexer (lexical analyser) is to scan the source code and break up each word into a list item. Once done it tak...

This is a simple parser which will parse an integer variable declaration token stream which we created in the previous example Simple Lexical Analyser. This parser will also be coded in python. What is a parser? The parser is the process in which the source text is converted to an abstract syn...
