As of October 2023, Korotkevich is the highest-rated programmer on CodeChef, [2] Topcoder, [3] AtCoder [4] and HackerRank. [5] On 30th August 2024, he achieved a historic rating of 4009 on Codeforces, becoming the first to break the 4000 barrier. [6] He was the highest-rated programmer on Codeforces [7] until 20 January 2024.
HackerRank categorizes most of their programming challenges into a number of core computer science domains, [3] including database management, mathematics, and artificial intelligence. When a programmer submits a solution to a programming challenge, their submission is scored on the accuracy of their output.
Modern C++ Design: Generic Programming and Design Patterns Applied is a book written by Andrei Alexandrescu, published in 2001 by Addison-Wesley. It has been regarded as "one of the most important C++ books" by Scott Meyers. [1] The book makes use of and explores a C++ programming technique called template metaprogramming. While Alexandrescu ...
A Fenwick tree or binary indexed tree (BIT) is a data structure that stores an array of values and can efficiently compute prefix sums of the values and update the values. It also supports an efficient rank-search operation for finding the longest prefix whose sum is no more than a specified value.
MemSQL uses lock-free skip lists as its prime indexing structure for its database technology. MuQSS, for the Linux kernel, is a CPU scheduler built on skip lists. [10] [11] Cyrus IMAP server offers a "skiplist" backend DB implementation [12] Lucene uses skip lists to search delta-encoded posting lists in logarithmic time. [citation needed]

For an arbitrary number of input sequences, the dynamic programming approach gives a solution in O ( N ∏ i = 1 N n i ) . {\displaystyle O\left(N\prod _{i=1}^{N}n_{i}\right).} There exist methods with lower complexity, [ 3 ] which often depend on the length of the LCS, the size of the alphabet, or both.
