HackerRank's programming challenges can be solved in a variety of programming languages (including Java, C++, PHP, Python, SQL, and JavaScript) and span multiple computer science domains. [ 2 ] HackerRank categorizes most of their programming challenges into a number of core computer science domains, [ 3 ] including database management ...
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.
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.
An integer programming problem is a mathematical optimization or feasibility program in which some or all of the variables are restricted to be integers.In many settings the term refers to integer linear programming (ILP), in which the objective function and the constraints (other than the integer constraints) are linear.
A universal constructor can be built which contains a Turing complete computer, and which can build many types of complex objects, including more copies of itself. [2] On November 23, 2013, Dave Greene built the first replicator in the Game of Life that creates a complete copy of itself, including the instruction tape. [ 48 ]
