Pseudocode

No standard for pseudocode syntax exists, as a program in pseudocode is not an executable program.

Pseudocode The pseudocode for the depth limited minimax algorithm is given below.

Algorithm The following pseudocode determines whether a year is a leap year or a common year in the Gregorian calendar (and in the proleptic Gregorian calendar before 1582).

A simple one is given in pseudocode below.

Depending on the writer, pseudocode may therefore vary widely in style, from a near-exact imitation of a real programming language at one extreme, to a description approaching formatted prose at the other.

Examples and pseudocode Example hashes These are examples of SHA-1 message digests in hexadecimal and in Base64 binary to ASCII text encoding.

Implementation The following pseudocode demonstrates how HMAC may be implemented.

Programmers may also start a project by sketching out the code in pseudocode on paper before writing it in its actual language, as a top-down structuring approach, with a process of steps to be followed as a refinement.

Pseudocode, flowcharts, drakon-charts and control tables are structured ways to express algorithms that avoid many of the ambiguities common in natural language statements.

Pseudocode resembles, but should not be confused with skeleton programs which can be compiled without errors.

Pseudocode The MD5 hash is calculated according to this algorithm.

The following pseudocode demonstrates this algorithm in a parallel divide-and-conquer style (adapted from Cormen et al. citation : 800 ).

This section gives pseudocode for adding or removing nodes from singly, doubly, and circularly linked lists in-place.
