 Algorithms and Combinatorics

**Algorithms** and **Combinatorics** are two important branches of mathematics and computer science, each focusing on different aspects of problem-solving and counting. ### Algorithms An **algorithm** is a step-by-step procedure or formula for solving a problem. It is a finite sequence of instructions or rules designed to perform a task or compute a function. Algorithms can be expressed in various forms, including natural language, pseudocode, flowcharts, or programming languages.
