Both StAX and SAX are a type of XML parser APIs. Here, API stands for Application Programming Interface and Parser is used to read and extract content from an XML document in desired format. From this line, it is clear that StAX and SAX are used to read XML documents. APIs are a modern way to migrate real time information on the Web. In this article, we will discuss the difference between StAX and SAX Parser in Java. StAX vs SAX Parser XML Its full form is eXtensible Markup Language and it is said to be a data description language. ... Read More

The TreeMap and TreeSet, both are the part of Collection Framework classes. There exist a few differences as well as a few similarities in their implementation and working. The TreeMap maintains key-value pair on the other hand the TreeSet does not have this feature. In this article, we will discuss the similarities between both classes of Collection Interface. Collection Interface In Java, collection is an object or we can say a container for simplicity that allows us to group several numbers of objects in a single unit. The collection interface is present at the root of all collection framework interfaces. ... Read More

Every time we do surfing on the Web or we download any file from Web, we take a risk of a virus attack. Maybe that file contains some malicious code that can breach the security and gain unauthorized access to system resources. If we are building an application that has users’ sensitive data, for example, a banking system contains confidential data like credit and debit card details, addresses, email and so forth. Then securing those data becomes our foremost priority. In this article, we are going to discuss a few standard practices for protecting the sensitive data of users in ... Read More

An array is a collection of elements of same data type, and each element in the array is identified by an index value. It is a simplest data structure and we can easily add or remove elements. Arrays in Python Python does not have a specific data structure to represent arrays. Here, we can use List an array. [9, 3, 1, 6, 9] We can use array or NumPy module to work with arrays in python. array('i', [1, 2, 3, 4]) The above array is the integer Array which is defined by the array module. In ... Read More

An array is a data structure consisting of a set of elements (values) of the same data type, each element is identified by an index value. And the elements can be directly accessed by using their index numbers. Arrays in Python Python does not have a native array data structure. Instead, we can use the list data structure, NumPy, or array modules. Here we will use list an array − [10, 4, 11, 76, 99] 0 1 2 3 4 The ... Read More

An array is a data structure consisting of a collection of elements of same data type, and each element is identified by an index. [2, 4, 0, 5, 8] 0 1 2 3 4 The integers 2, 4, 0, 5, 8 are the array elements and 0, 1, 2, 3, 4 are the respective index values of the array elements. In The article below, we will discuss the python program to find common elements between two arrays. Input Output Scenarios Assuming we have two arrays A and B. And the resultant ... Read More

In C++ we have a predefined function sqrt that returns the square root of any number. The Rotating Caliper’s Method is the technique used to solve the algorithmic or computational geometry. Visual Representation of Rotating Caliper’s MethodThe hand rotation shows the real example of a rotating caliper graph, whenever the hand rotates the perpendicular direction is shown. We can also understand this concept by using a polygon shape. In this article, we are going to find the maximum distance of two coordinate points using Rotating Caliper’s Method. Syntax The following syntax used in the program − vector name ... Read More

A matrix is a rectangular array where the set of numbers arranged in rows and columns. And it is called as an m X n matrix where m and n are the dimensions. If a matrix contains a very less number of non-zero elements compared to the zero elements then it is called a sparse matrix. [0, 0, 3, 0, 0] [0, 1, 0, 0, 6] [1, 0, 0, 9, 0] [0, 0, 2, 0, 0] The above matrix is 4X5 matrix here most of the numbers are zero. Only a few elements are non-zero so that we can ... Read More

A matrix is a two-dimensional array of many numbers arranged in rows and columns. A square matrix (whose rows and columns has same number of elements) has two diagonals. One is the Primary diagonal - located from the top left corner to the bottom right corner of a square matrix. And the second one is the Secondary diagonal - located from the top right to the bottom left corner. For a square matrix if all the elements below the Primary diagonal are zero then it is called the Upper Triangular Matrix. [1, 3, 4] [0, 5, 6] [0, ... Read More

Linear search is the simplest method of searching for an element in an array. It is a sequential searching algorithm that starts from one end and checks every element of the array until the desired element is found. Recursion means a function that calls itself, while using a recusive function we need to use any loop to generate the iterations. The below syntax demonistrates the working of a simple recursion function. def rerecursiveFun(): Statements ... rerecursiveFun() ... rerecursiveFun Linear Search of an Element ... Read More
