• at_least_n() - Check if at least n elements in an iterable satisfy a given predicate

• sort_dict_keys() - Sort dictionary keys using a given order list (ascending or descending)

• affine_permutation_generator() - Generate a memory-efficient pseudo-random permutation of [0, n)

• feistel_permutation_generator() - Generate a memory-efficient pseudo-random permutation of [0, n) using a Feistel network

• upsert_in_dataframe() - Insert or update a row in a Polars DataFrame based on primary keys
