Python package providing flexible tree data structures for organizing lists and dicts into sections. Sections is designed to be: Intuitive: Start quickly, spend less time reading the docs. Scalable: Grow arbitrarily complex trees as your problem scales. ...
pybktree is a generic, pure Python implementation of a BK-tree data structure, which allows fast querying of "close" matches (for example, matches with small hamming distance or Levenshtein distance). This module is based on the algorithm by Nick Johnson in his blog article on BK-trees. The...
It is, in principle, astatic structure; that is, it's a structure that cannot be modified once it's built. Complexity: A segment tree of a set I of n intervals uses O(nlogn) storage and can be built in O(nlogn) time. Segements trees support searching for all the intervals that co...
