  2. Lexicographic order - Wikipedia

    en.wikipedia.org/wiki/Lexicographic_order

    The lexicographical order is one way of formalizing word order given the order of the underlying symbols. The formal notion starts with a finite set A, often called the alphabet, which is totally ordered. That is, for any two symbols a and b in A that are not the same symbol, either a < b or b < a.

  3. Zen of Python - Wikipedia

    en.wikipedia.org/wiki/Zen_of_Python

    The Zen of Python is a collection of 19 "guiding principles" for writing computer programs that influence the design of the Python programming language. [1] Python code that aligns with these principles is often referred to as "Pythonic". [2] Software engineer Tim Peters wrote this set of principles and posted it on the Python mailing list in ...

  4. Generalized suffix tree - Wikipedia

    en.wikipedia.org/wiki/Generalized_suffix_tree

    A suffix tree for the strings ABAB and BABA is shown in a figure above. They are padded with the unique terminator strings $0 and $1. The numbers in the leaf nodes are string number and starting position. Notice how a left to right traversal of the leaf nodes corresponds to the sorted order of the suffixes.

  5. Radix sort - Wikipedia

    en.wikipedia.org/wiki/Radix_sort

    In computer science, radix sort is a non-comparative sorting algorithm.It avoids comparison by creating and distributing elements into buckets according to their radix.For elements with more than one significant digit, this bucketing process is repeated for each digit, while preserving the ordering of the prior step, until all digits have been considered.

  6. Subsequence - Wikipedia

    en.wikipedia.org/wiki/Subsequence

    Subsequence. In mathematics, a subsequence of a given sequence is a sequence that can be derived from the given sequence by deleting some or no elements without changing the order of the remaining elements. For example, the sequence is a subsequence of obtained after removal of elements and The relation of one sequence being the subsequence of ...

  7. Riemann zeta function - Wikipedia

    en.wikipedia.org/wiki/Riemann_zeta_function

    Hardy and J. E. Littlewood formulated two conjectures on the density and distance between the zeros of ζ (⁠ 1 / 2 ⁠ + it) on intervals of large positive real numbers. In the following, N(T) is the total number of real zeros and N 0 (T) the total number of zeros of odd order of the function ζ (⁠ 1 / 2 ⁠ + it) lying in the interval (0, T].

  8. Universal hashing - Wikipedia

    en.wikipedia.org/wiki/Universal_hashing

    Consider two strings ¯, ¯ and let be length of the longer one; for the analysis, the shorter string is conceptually padded with zeros up to length . A collision before applying h i n t {\displaystyle h_{\mathrm {int} }} implies that a {\displaystyle a} is a root of the polynomial with coefficients x ¯ − y ¯ {\displaystyle {\bar {x}}-{\bar ...

  9. Newton's method - Wikipedia

    en.wikipedia.org/wiki/Newton's_method

    Newton's method is one of many known methods of computing square roots. Given a positive number a, the problem of finding a number x such that x2 = a is equivalent to finding a root of the function f(x) = x2 − a. The Newton iteration defined by this function is given by.
