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 ...
First self-published in 2008, her book Cracking the Coding Interview provides guidance on technical job interviews, and includes solutions to example coding interview questions. [5] A followup was published in 2025 covering issues in recruitment, job hunting and behavioral interviews alongside material on big O notation , leetcode , algorithms ...
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.
Users of Stack Overflow can earn reputation points and "badges"; for example, a person is awarded 10 reputation points for receiving an "up" vote on a question or an answer to a question, [12] and can receive badges for their valued contributions, [13] which represents a gamification of the traditional Q&A website. Users unlock new privileges ...
In computer science, a programming language is said to have first-class functions if it treats functions as first-class citizens.This means the language supports passing functions as arguments to other functions, returning them as the values from other functions, and assigning them to variables or storing them in data structures. [1]
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 ]
k-means clustering is a method of vector quantization, originally from signal processing, that aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean (cluster centers or cluster centroid), serving as a prototype of the cluster.
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.
