In this article, we will write a C++ program that implements a Min Heap. A Min Heap is a binary tree where the value of each node is less than or equal to the values of its children. We will explain how to create a Min Heap using arrays and implement operations like insertion and deletion. The article will cover the following topics: What is a Heap? Types of Heap Representing a Heap What is a Min Heap? What ... Read More
In this article, we'll explain the difference between private and protected access specifiers in C++. Access specifiers in C++ control who can access the variables and functions inside a class. Two commonly used specifiers are private and protected. Private members are accessible only within the class, while protected members can be accessed by the class and its derived classes. We'll show how each specifier works in C++, especially with inheritance, using simple examples to make it easy to understand. Private Access Modifier When we declare a class member as private, it means that this member is only accessible within ... Read More
In this article, we will explain the difference between Insertion Sort and Selection Sort. These are two basic sorting algorithms used to arrange numbers in order. We will look at how they work, how fast they are, and when to use each one. By the end, you'll have a clear understanding of the differences between Insertion Sort and Selection Sort. Here's what we'll cover: What is Insertion Sort? What is Selection Sort? Complexity Comparison Key Differences Between Insertion Sort and Selection Sort ... Read More
In C/C++, we usually use the sizeof operator to find the size of an array. However, once an array is passed to a function, its size is lost. So, how can we find the size of an array without using sizeof? For example, consider this array: int arr[] = {1, 2, 3, 4, 5}; Without using sizeof, we can use a loop to count the number of elements in the array. In this article, we'll show you different methods to find the size of an array in C or C++ without using sizeof, with clear and simple examples. ... Read More
The XML is the markup language used to transfer the data. The XML syntax is the same as the HTML, whereas the tags are predefined in HTML and not in XML. This offers us to store the data between the opening and closing tags. In Python, dictionaries store data as key-value pairs. We can serialize a dictionary to XML format using two popular libraries: dict2xml (widely used) dicttoxml ... Read More
The Object class is the superclass of every single class in Java. This position implies that every class in Java, even if a built-in class or function like String or a user-defined one, directly or indirectly inherits from Object. Understanding the Object Class The Object class provides fundamental methods that every Java object inherits. Even if a class does not explicitly extend another class, it implicitly extends Object. Below is a demostration of the same − class Example { //This class implicitly extends to an Object } Why Does Every Class Inherit from ... Read More
In Java there are various data types present, the String type often leads to confusion regarding whether it is a primitive data type or an object(non-primitive data type ). Primitive Data Types in Java Primitive data types are the most basic data types the Java language provides. Primitive data types are not objects and do not have methods or properties. Eg: int (32-bit), float(32-bit), double(64-bit ), etc. What is String in Java? A string is not a primitive data type. Java.lang package provides the String class therefore, it is an object type. The String class provides methods to manipulate and operate ... Read More
Understanding the Operator in Python The is one of the operators available in Python. The present version that we are using is Python 3. The previous version was Python 2. Some of the operators in Python 2 don't support in Python 3. is used in Python 2, which is not supported in Python. The operator != is used in Python 3. The functionality of the or != is to represent not equal to. The output of these operators is in the format of Boolean values True or False. Syntax The following is the syntax for using ... Read More
Python Program to Count Total Bits in a Number To calculate the total bits in a number, convert it to binary using the bin() function. A bit represents data as 0 or 1, and 8 bits make a Byte. Bits are essential for data transmission, storage, and arithmetic operations, and bitwise operations are also possible. The output of bin() starts with 0b, followed by the binary digits. To find the total bit count, remove the leading 0b after conversion. Syntax Following is the Syntax for the bin() function. Where, number is the number to be converted into binary format variable_name ... Read More
Python object is belongs to the object oriented programming language. We previously have idea and knowledge regarding the python object. provides several built-in functions that help you inspect various aspects of objects. Some of these methods, including help(), type(), dir(), id(), hasattr(), getattr(), and callable(). Using the help() function If we want to inspect the python object we have a built function of python named help(). That provides documentation about an object, including its methods and attributes. Example In the following code, we imported the power function from the math module. Next we applied the inbuilt function help() on power ... Read More
