5. Algorithms Algorithm Pseudocode
A step by step, list of instructions that if followed exactly will solve the problem under consideration.
Pseudocode
An informal description of an algorithm (in English language) which can easily translate into a high-level language (like Python).
Always think about a general solution then write it in a programming language so the computer can do it. CS

6. Algorithms The algorithm described in pseudocode must be Unambiguous
There are precise instructions for what to do at each step and where to go next.
Executable
Each step can be carried out in practice.
Terminating
It will eventually come to an end. CS
