The simplest way to specify the logic for an algorithm is to write the higher-level description of an algorithm in a semi-structured way, called pseudocode. Before writing the logic in pseudocode, it is helpful to first describe its main flow by writing the main steps in plain English. Then, this English description is converted into pseudocode, which is a structured way of writing this English description that closely represents the logic and flow for the algorithm. Well-written algorithm pseudocode should describe the high-level steps of the algorithm in reasonable detail, even if the detailed code is not relevant to the main flow and structure of the algorithm. The following figure shows the flow of steps: 

Note that once the pseudocode is written (as we will see in the next section), we are ready to code the algorithm using the programming language of our choice.
