What problem does it solve?

Prolog list processing patterns are essential for efficiently manipulating lists, pattern matching, and transforming data in logic programs.

Core Features & Use Cases

• List structure concepts (head/tail, [|], difference between [H|T] and plain lists)
• Fundamental predicates: member/2, append/3, length/2, last/2, reverse/2
• Higher-order and multi-directional predicates: maplist, include, exclude, foldl, msort, sort
• Patterns: select/3, permutation/2, nth0/nth1, flatten/2, pairs_keys_values
• Difference lists and their use for O(1) appends
• List comprehension analogs via findall/bagof/setof
• Accumulators and tail recursion examples
• Real-world scenario: building a simple permutation generator or filtering elements

Quick Start

Experiment with sample queries in your Prolog environment to try patterns described here.
