Python provides a powerful library named Matplotlib that creates visual representations in the form of plots and graphs. One of the many features of this library is the ability to plot multiple plots within a single figure that are useful when comparing different datasets or visualizing relationships between multiple variables. We are going to explore the built-in method named 'subplots()' of Matplotlib that is used to plot multiple plots. Python program to plot multiple plots in Matplotlib Before jumping to the program directly let's familiarize ourselves with subplots() method of Matplotlib. subplots() method With a single ...

Python provides a powerful library named Matplotlib that creates visual representations in the form of plots and graphs. One of the many features of this library is the ability to plot vertical lines that are used to add a reference line or highlight a specific point on the given plot. The built-in methods 'axvline()', 'vlines()', and 'plot()' of Matplotlib are used to plot vertical lines with customizable parameters such as position, color, and linestyle. We are going to explain these methods with the help of example programs. Plotting vertical line using Matplotlib Let's discuss the in-built methods of ... Read More
Segment Tree is a versatile data structure designed for answering range queries and performing updates on arrays in logarithmic time complexity, where each node stores information related to a specific range of elements in the array. In the context of the Longest Increasing Subsequence (LIS) problem, which requires determining the length of the longest subsequence of a given sequence in which the elements are sorted in increasing order, Segment Trees can be utilized to efficiently compute the Length of Longest Increasing Subsequences in an array. This approach significantly reduces the time complexity compared to traditional methods and has ... Read More
Classification of algorithms helps in selecting the most suitable one for a specific task, enabling developers to optimize their code and achieve better performance. In computer science, algorithms are sets of well-defined instructions used to solve problems or perform specific tasks. The efficiency and effectiveness of these algorithms are crucial in determining the overall performance of a program. In this article, we will discuss two common approaches for classifying algorithms, namely, based on their time complexity and based on their design technique. Syntax The syntax of the main function used in the codes for both approaches − int ... Read More
The expression "K-length subarrays" pertains to successive subarrays having precisely K elements. Grasping and working with subarrays is crucial for resolving various issues in fields such as dynamic programming, computational geometry, and data analysis. Another vital concept in array manipulation and statistics is the median. The median of an array represents the middle value when the elements are sorted in ascending order. In the case of an even number of elements, the median is the average of the two central values. The median constitutes a durable measure of central tendency, as it is less vulnerable to extreme values or outliers ... Read More
When engaged in computer programming, it is sometimes necessary to locate the minimum weight of a subtree that originates from a specific node, with the condition that the subtree must not contain any nodes farther than D units away from the specified node. This problem arises in various fields and applications, including graph theory, tree-based algorithms, and network optimization. The subtree constitutes a subset of a larger tree structure, with the specified node serving as the root of the subtree. The subtree encompasses all the descendants of the root node and their connecting edges. The weight of a node refers ... Read More
A foremost series summation array is an assemblage that accumulates the sum of interlacing elements up to an express index. It is a widely utilized tactic in the reconfiguration of assemblages to refine time complexity. Fenwick Tree, also recognized as Binary Indexed Tree (BIT), is a form of database that proficiently modernizes components and computes a preceding series summation in logarithmic time complexity. Within this article, we shall confer on how to disclose the lesser extreme boundary of a given value, referred to as K, from a series summation array with modernizations utilizing Fenwick Tree in C++. Syntax The ... Read More
Python has become one of the most popular programming languages in recent years, with applications ranging from data analysis to web development to machine learning. One of the key libraries for data analysis in Python is Pandas, which provides powerful data structures like DataFrames and Series for handling and manipulating data. In particular, Pandas Series are one-dimensional arrays that can hold any data type, making them versatile tools for data analysis and manipulation. In this tutorial, we will explore how to convert a Pandas Series to a Python list. Converting a Series to a list can be useful in situations ... Read More
Graph theory encompasses the study of connected components, which are subgraphs in an undirected graph where every pair of vertices is linked by a path, and no other vertices are connected to it. In this article, we will delve into the utilization of the C/C++ programming language to determine if two vertices, X and Y, belong to the same connected component in an undirected graph. We will elucidate the syntax and rationale of the method before elucidating at least two diverse approaches to tackle this problem. Furthermore, we will provide concrete code examples and their corresponding outcomes for each ... Read More
Sometimes, we may need to store a list as the value of a dictionary key and in the future, for some reason we require to update or add more elements to that list. Python provides several ways for appending elements to a list in the Python dictionary. In this article, we are going to use a built-in methods 'append()', 'update()' and '+=' operator for this purpose. Program for appending to a List in Python Dictionary Before jumping to the program directly let's familiarize ourselves with List and Dictionary in Python. List It is an ordered ... Read More
