Why are algorithms not written in a particular programming language?

Algorithms are abstract concepts that describe a step-by-step procedure for solving a problem, independent of any specific programming language. They can be expressed in natural language, pseudocode, or flowcharts, which allows for clarity and focus on logic rather than syntax. This language-agnostic nature enables the same algorithm to be implemented in multiple programming languages, adapting to the specific constructs and features of each. Thus, the core idea remains consistent, while the implementation may vary.
