Binary Search

Binary search is an efficient algorithm used to find an element in a sorted array or list by repeatedly dividing the search range in half. It compares the target value to the middle element, narrowing the search to either the left or right half. It runs in O(log n) time complexity.

System Design
System design is the process of defining the architecture, components, modules, interfaces and data flow of a system to meet specific requirements. It focuses on creating scalable, efficient and maintainable solutions, covering both high-level design (HLD) and low-level design (LLD). Essential for building reliable, high-performance software systems.
String
String is a data type used in most of the programming language. String is a sequence of characters and can contain letters, spaces , symbols ,numbers etc. commonly used for text, though sometimes for arbitrary data.
Coding Problems
Coding problems are exercises designed to test a programmer’s ability to write logic, solve challenges and apply algorithms or data structures. They help improve problem-solving skills, logical thinking and coding efficiency. Common in interviews and competitive programming, coding problems range from simple tasks to complex algorithmic challenges, preparing developers for real-world software development scenarios.
git branch
git branch is a command used to manage branches within a Git repository. It allows developers to create, list, rename and delete branches. Branches enable parallel development, feature isolation and safe experimentation without affecting the main codebase. Using git branch helps teams organize work efficiently and maintain clean, structured workflows during development.
