The method of describing computer algorithms using a combination of natural language and programming language is called Pseudocode.

Pseudocode is a high-level description of an algorithm that blends the syntax of programming languages with the readability of natural language. This approach allows programmers and computer scientists to express the logic of their algorithms without getting bogged down in the specific syntax rules of any given programming language.

The primary purpose of pseudocode is to plan and communicate algorithms clearly between developers. It serves as a bridge between the problem statement and actual implementation, making it easier to understand the underlying logic without requiring knowledge of coding details. As a result, pseudocode can help in debugging and verifying algorithms before they are coded into a specific programming language.
