Task: Text Categorization
Input (English): Takoka developed one version of this data structure called the 2-3 variety, while other versions of this structure include the skew and leftist varieties. Tarjans algorithm can be used to construct them in linear time, and Dijkstras algorithm often uses the Fibonacci type. This structures namesake sorting algorithm has a worst-case runtime of big O of n log n, and operations allowed within these structures include delete-max and merge. FTP, name these data structures used to implement priority queues, that consist of a tree in which each child node has a key less than that of the parent node.
Output (English): Science
