In the programming world, indentation has been essential for structuring code. Unlike most languages, which use braces and keywords to mark code blocks, Python uses whitespaces and indents only to distinguish code blocks as they return.
Such a feature is crucial to how Python programs are written, read, and executed, as well as the heart of the role of the language in the world of programming. This article unravels the mysteries of space and invades the indentation of Python, importing its rules, benefits, and shortcomings and giving the techniques for their use.
To learn how to make a simple html page, we need some text editor, for example, Windows Notepad. But it is more convenient to use a special editor like Sublime Text that has syntax highlighting. And to view html page use any Internet browser. Simply open it by double-clicking. Continue reading
Create Java gravity calculator, able to determine the object’s final position after falling through the Earth’s atmosphere through the predetermined time. The initial parameters include: gravity (-9.81), falling time (10 seconds), as well as initial position and initial velocity of the object (both set to 0 by default). However the user should be able to modify the last 3 parameters according to his liking, with the calculator providing him with corresponding final position each time one of parameters changes.

An array is considered to be balanced if it can be divided into two parts so that the sum of the elements of the left-hand side is equal to the sum of the elements of the right-hand side. For example, the array [1, 1, 1, 2, 1] can be divided into two parts: [1, 1, 1] and [2, 1]. The sum of the elements of both parts is equal to 3, thus, the array is balanced. Continue reading
The Euclidean algorithm is an effective algorithm for finding the greatest common divisor of two integers. It is named after the Greek mathematician Euclid, who invented in VII century.
In the most simple case, Euclidean algorithm is applied to a pair of positive integers and generates a new pair consisting of a smaller number, and the modulo between the larger and the smaller number. The process is repeated until the found number will be the greatest common divisor of the original pair.
The extended Euclidean algorithm also finds such coefficients x and y that:

2. Create a simple IndexController that returns the plain text “Hello” for any request. Use the Java configuration instead of xml configuration. Continue reading
An IP address conflict occurs when two computers in a network are assigned the same IP address. When this happens, it renders one or both computers unable to connect to a network resource or perform other network operations. Almost all operating systems notify the user via pop-up notification when an IP conflict is detected with another computer. This network problem, although rare, is a very real issue to end-users and network administrators. Continue reading
