The dictionary problem is the classic problem of designing efficient data structures that implement associative arrays. [2] The two major solutions to the dictionary problem are hash tables and search trees .

Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [33] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...
In this example, we will consider a dictionary consisting of the following words: {a, ab, bab, bc, bca, c, caa}. The graph below is the Aho–Corasick data structure constructed from the specified dictionary, with each row in the table representing a node in the trie, with the column path indicating the (unique) sequence of characters from the root to the node.
Patrizia Mosca, Chief operating officer at Kurzgesagt, speaks at the Internet Days in Stockholm, 2018.. The Kurzgesagt YouTube channel was created on 10 July 2013 (with their first video coming out on 12 July 2013), shortly after the founder, Philipp Dettmer, graduated from Munich University of Applied Sciences.

The Free Software Foundation argued that the choice-of-law clause was incompatible with the GNU General Public License. BeOpen, CNRI and the FSF negotiated a change to Python's free-software license that would make it GPL-compatible. Python 1.6.1 is essentially the same as Python 1.6, with a few minor bug fixes, and with the new GPL-compatible ...
Each terminal node is associated with a list of URLs—called occurrence list—to pages that match the keyword. The trie is stored in the main memory, whereas the occurrence is kept in an external storage, frequently in large clusters , or the in-memory index points to documents stored in an external location.
A trapdoor function is a collection of one-way functions { f k : D k → R k} (k ∈ K), in which all of K, D k, R k are subsets of binary strings {0, 1} *, satisfying the following conditions:
