Could you explain #likeimfive Psuedocode & its purpose?

What:

Pseudocode visualizes the steps of an algorithm, often in a human language (English, Spanish, etc.). It is usually not executable (executable code is code which produces some sort of result upon execution).

Why:

It allows people to grasp concepts / ideas before implementation, since the implementation and result of an algorithm is a cost (time, energy, money, etc.) in itself.

Real life example:

You want to program a machine to move items between location A and B. Before programming executable code to perform said task, you are given pseudocode of two algorithms, algorithm 1 and algorithm 2. By inspecting the pseudocode, you realize that the cost of algorithm 1 is 10 seconds (execution time) and cost of algorithm 2 is 20 seconds (execution time), and so you choose to implement algorithm 1.

Very well explained sir, thanks!

Yeah. Not quite code, not quite humanspeak. I might use basic programming concepts like loops, or perhaps recursion, but speaking in general terms instead of getting caught up in the details of executable code.
