subsequences

This library provides predicates for working with subsequences represented using lists, including generation, search, contiguous subsequence operations, and random selection. The following categories of predicates are provided:

  • Generation operations - Predicates for generating subsequences and variants thereof.
  • Ordering variants - Predicates that support an additional order argument (default, lexicographic, or shortlex) for controlling output order.
  • Filtered generation - Predicates for generating specific types of subsequences (combinations, permutations).
  • Indexed access - Predicates for direct access to subsequences at specific positions.
  • Searching and matching - Predicates for finding specific subsequences with desired properties.
  • Prefix and suffix operations - Predicates for checking and finding prefixes and suffixes.
  • Contiguous subsequences - Predicates for working with contiguous subsequences (subslices, sliding windows).
  • Random selection - Predicates for randomly selecting subsequences.
  • Constrained operations - Predicates for generating subsequences with specific constraints.
  • Utility predicates - Predicates that support subsequence operations. Dedicated combinations and permutations libraries are also available for focused APIs on those operations.
