Introduction In this tutorial, we implement examples using C++ to find the number of times an input string occurs in an array of the range [l, r]. Only lowercase alphabets are used in the string array to resolve this task. Different strings are stored in the string array and traversed ... Read More

Introduction In this tutorial, we implement 2 examples using C++ to find the minimum number of substrings in a given string. Those substrings are all powers of 5 that means, the substrings are the factors of the number 5. To implement the example, take an input binary string and generate ... Read More

Introduction In this tutorial, we use C++ programming concepts to implement examples to find the minimum cost to modify a string. String modification includes operations to change one string into another string. String operations include insertion, deletion, and substitution. We predefined the cost of each operation. You can choose the ... Read More

Introduction A palindrome is one that reads the same forward and backward. An example of a palindrome string is Mam. In this tutorial, we use C++ programming to find the maximum length palindrome of a string by predefining the range of characters. Our task is to find the ... Read More

Introduction In this tutorial, we implement an approach to find the longest substring of only 4 using the first N characters of the infinite string. Infinite string using 4 looks like this: “44444444……” and for this string we define the length of characters to consider for solving the task. To ... Read More

Introduction In this tutorial, we will discuss probabilistic data structures in detail. This tutorial will cover the meaning of a Probabilistic Data Structure, its types, and its benefits. When dealing with large data sets or Big Data, basic data structures that use hashtables or HashSets would not be effective enough. ... Read More

Introduction In this tutorial, we implement an approach to find the kth substring after sorting all the substrings according to some conditions for a given string and the value of k. The condition to sort the substring is that the substrings are alphabetical while producing the substring in the order ... Read More

Introduction In this tutorial, we implement two examples using C++ programming concepts to generate all permutations of an input string. Permutation of a string is the number of ways a string can be arranged by interchanging the position of characters. We also include some constraints or limitations. All permutations or ... Read More

Introduction In this tutorial, we implement an approach to capitalizing the first and last characters of each word in the input string. By iterating over the input string str, each word's starting and ending letters are capitalized. We implement this problem using C++ programming in two ways. Let's start ... Read More

Introduction In this tutorial, we introduce an approach to sorting an alphanumeric string such that the position of alphabets and numbers remains unchanged. In this approach, we use C++ functions and take an input string containing characters and numbers. Generate the string without changing the alphabet and number positions. The ... Read More
