We will be given an array and have to choose an element from it and add that element to the sum. After adding that element to the sum, we have to remove three elements from the array if they exist current number, current number -1, and current number + 1. By this method we will make the array empty and will get a sum. At the end, we have to make the sum maximum. Input: [ 1, 2, 3] Output: 4 Explanation At first, we can have three moves, delete 1, 2, or 3. Let ... Read More

In C++, the trie has an advanced data structure that is used for storing the collection of trees. The word tries came from the word retrieval and it is known as a digital tree or prefix tree. Let’s take an example of all possible joint by taking a given list of strings. We are defining the string input as {“tutor”, “true”, “tuo”} We can observe that the different string of characters is connected to the single string of the character. So here t and u are the list of characters in the string that joints all possible strings. In ... 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

Machine Learning ML is the investigation of PC calculations that learn without being unequivocally modified by people. They accomplish this by ingesting and preparing information, which assists them with recognizing examples and patterns. ML is generally pertinent in healthcare, marketing, medical services, logistics, human resources, energy, protection, e-commerce, manufacturing, art & creativity, finance, transportation, automobile, government & surveillance, insurance, and digital media and entertainment. Huge corporate goliaths like Apple, Google, Microsoft, IBM, and to a greater extent, use ML. In addition to the tech monsters, however little and mid-sized new companies likewise depend on ML. Most tech organizations use AI ... Read More

The longest common prefix problem is a well-known computer science problem that is frequently encountered when working with strings or lists. It entails determining the string or list element with the longest common prefix. When it comes to linked lists, there are several approaches that can be taken. One common approach is to traverse the linked list and compare the characters of each node in the list until a mismatch is found. The longest common prefix up to the point of mismatch is considered. Linked List A linear linked list can be defined as a collection of variable number of ... Read More

The evaluation of all equation in an interval [L, R] give us a range of values for those variables. Examples of how this may be used include modelling, data analysis, and problem-solving scenarios. In this situation, we define equations variable values for all point in range. Hence can be done by specifying the step size of the range and evaluating the equation for each variable value inside the range. Specifications It may be called a request for information asked to database. Data is extracted using specific commands when certain requirements are met. To acquire, filter, sort, and summarize data from ... Read More

What are the Specifications of Using String? To solve a specific challenge involving the given string S. The string S contains only lowercase English letters, and certain constraints must be followed while removing characters. The given constraints are − There are lowercase English letters in string S. A character can only be deleted if it appears more than once in string. Only characters that appear consecutively can be deleted. The following steps can be used to remove characters from string S − Find all characters that appear more than once as you iterate over string S. Find all of ... Read More

String manipulation-related concepts like The Sum of indices of Characters deleted to obtain an Empty String are frequently utilized in programming challenges and competitions. The result is then computed using the sum of the eliminated characters' indexes. The Sum of indices of Characters deleted to obtain an Empty String is a practical idea in string manipulation that may be used to solve a variety of programming difficulties and challenges. Problem Approach We must first comprehend the problem statement and given criteria to find total of character indices eliminated to produce empty string. Given string S, the objective is to determine ... Read More

The Fenwick Tree is a type of data structure, which enables range updates and range searches with O(log n) time complexity, also called as binary indexed tree (BIT) The fundamental concept is to keep frequency array for every letter in string, with frequency of i-th character being recorded at index i in frequency array. The frequency array can then allow range updates and range queries using Fenwick Tree. Problem Approach You can use following queries to extract Kth biggest character from string with updates in range [L, R] − Build segment tree − Create segment tree first, in which ... Read More

An array can be successfully updated and put through to range queries thanks to segment trees. With updates, we can use data structure known segment tree to count no. of elements in Array which are larger than or same as no. Query − Find out how many items exist in [l, r] range that are larger than or similar to x. Give 0 if range [l, r] lies entirely beyond segment that current node of segment tree represents. Count no. of elements in range [l, r] which is larger than or similar to x if interval [l, r] ... Read More
