In computer science, string manipulation is an essential topic that involves operations such as concatenation, substring, reversing, and more. One common problem related to string manipulation is to remove all 0s from a binary string. In this article, we will discuss an algorithm to solve this problem using a minimum number of non-adjacent pair flips. Problem Statement Given a binary string, we have to remove all 0s from the string using the minimum number of non-adjacent pair flips. A flip is defined as selecting two adjacent characters and swapping them. In other words, we need to find the minimum number ... Read More

In this article, we delve into a fascinating problem of string manipulation and character encoding in computer science. The task at hand is to minimize the number of swaps between same-indexed characters of two strings to make the sum of ASCII values of characters in both strings odd. We tackle this problem using C++, a robust and versatile programming language favored by many software developers. Understanding ASCII ASCII, short for American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices that use text. Problem Statement ... Read More

Minimizing steps defined by a string required to reach the destination from a given source is a common problem in computer science. It involves finding the shortest path from a starting point to a destination point based on a string of directions. In this article, we will discuss how to solve this problem in C++, provide an example, and discuss the test cases. Problem Statement Given a starting point (x, y) on a 2D plane and a string of directions (N, S, E, W), we need to find the shortest path to reach a destination point (x', y') from the ... Read More

In this article, we will discuss a fascinating algorithmic problem: "Minimize replacement of characters to its nearest alphabet to make a string palindromic."
