Introduction In the current world, handling data is the most challenging task for organizations with a high volume of data and with the development of data science and machine learning it has become easier to access. And the Python language plays a vital role in dealing with this data, as the data present can be relevant or irrelevant to each other. When they have some relevancy, it can be stored combinable with the other data or simply the aggregating of the data. In this, it combines the elements with similar characteristics and attributes they belong to. To do this process, ... Read More
In this problem, we will count the minimum number of characters we need to insert to remove all adjacent duplicate characters. To solve the problem, we need to count the total number of adjacent duplicate character pairs. Problem statement – We have given a string named str containing N alphabetical characters. We need to find the total number of different characters we require to add to the string such that the resultant string shouldn’t contain any adjacent duplicated characters. Sample examples Input str = "ccddrt" Output 2 Explanation – We need to insert one character ... Read More
In this problem, we will traverse each boundary of the given binary tree in the given order. We will use the recursive approach to traverse each boundary of the binary tree one by one. However, we will also learn the iterative approach using a stack to traverse the binary tree's boundary and increase the code's performance. Problem Statement We have given a binary tree, and we need to traverse each boundary of the tree in the given order. Traverse left boundary in top to bottom manner. Traverse bottom boundary from left to right. Traverse the right boundary from bottom ... Read More
Introduction Undirected graphs are an essential component of computer science and graph theory, representing a group of nodes connected by edges without any directionality. One common problem associated with undirected graphs is the counting of simple cycles or circuits, which are closed paths that visit each vertex only once. In this article, we will explore how to get total count of the given undirected graph with N vertices using the powerful programming languages C and C++. Undirected Graph Before we jump into coding, let's ensure everyone grasps what constitutes a simple cycle within an undirected graph. Let us consider an ... Read More
Introduction Graph coloring may be an essential issue in graph hypothesis. The DSatur algorithm presents a compelling approach to play down the utilization of colors while performing chart coloring. By deliberately selecting vertices with the most noteworthy immersion degree, DSatur guarantees an optimized color task that maximizes color differing qualities and minimizes color utilization. In this article, we explore the DSatur calculation for chart coloring and its utilization utilizing C++. The calculation decides its title from the two key concepts it utilizes: Degree and Submersion. It considers the degrees of the vertices and their inundation degrees, which speak to the ... Read More
A List is a type of data structure in Python language that can store elements of different data types within these “[]” brackets. The order in which data can be sorted will be either ascending or descending. In a list when the preceding element is greater than the next element then it follows descending order and on the other hand, when the preceding element is less than the next element then it follows ascending order. Utilizing three distinct approaches, the ways are given verifying for descending Sorted list in python. Approaches Approach 1 − Using iteration method Approach 2 ... Read More
Introduction In graph hypothesis, the user will understand to find the length of the longest expanding grouping of nodes in a specified graph. It includes deciding the longest way in a chart where each hub within the way features a strictly increasing esteem compared to its past node. In this article, we are going investigate three approaches to unravel this issue utilizing C++. Each approach will be clarified in detail, counting the calculation, step-by-step execution, and yield. To guarantee consistency, we'll utilize the same input for all three approaches, and they will create the same yield. Approach 1: Depth-First Search ... Read More
Introduction The task of making the lexicographically smallest string by replacing characters according to a given relation poses a captivating challenge in string control. The objective is to modify the characters inside the input string, following to the required substitution rules, in arrange to get the littlest lexicographic order. In this article, we'll focus on solving this issue utilizing C++. We are going investigate three approaches to handle this issue, each utilizing a one of a kind technique and algorithmic method. These approaches are planned to supply distinctive bits of knowledge into understanding the issue, considering variables such as effectiveness, ... Read More
In this problem, we require to find the minimum jumps required to make to reach the largest and smallest character in the given string. We can move to the next or previous character in one jump. We can solve the problem by finding the position of the lexicographically largest and smallest character in the given string. After that, we can find the minimum jumps required to the found indexes from the left and right sides. Problem statement – We have a string str of length N containing the alphabetical characters in the uppercase. We need to find the minimum number ... Read More
Introduction Graph theory plays a crucial part in understanding a wide run of real-world issues, counting course optimization, organize examination, and task planning. One interesting issue inside graph theory is the seek for a Hamiltonian way, a way that visits each node in a graph exactly once. This issue has applications in zones such as circuit plan, DNA sequencing, and coordination’s arranging. In this article, we dig into the investigation of diverse approaches to decide on the off chance that it is conceivable to visit each hub in a given chart precisely once, based on certain conditions. We center on ... Read More
