SEMANTIC ANALYSIS

The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by leetcode.com.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics
Knowledge Confidence: 74% Arrow up

Knowledge is a familiarity, awareness or understanding of someone or something, such as facts, information, descriptions, or skills, which is acquired through experience or education by perceiving, discovering, or learning.

Skill Confidence: 73% Arrow up

A skill is the ability to carry out a task with pre-determined results often within a given amount of time, energy, or both.

Skills can often be divided into domain general and domain-specific skills.

For example, in the domain of work, some general skills would include time management, teamwork and leadership, self-motivation and others, whereas domain-specific skills would be useful only for a certain job.

Skill usually requires certain environmental stimuli and situations to assess the level of skill being shown and used.

Educational technology Confidence: 72% Arrow up

Educational technology is defined by the Association for Educational Communications and Technology as "the study and ethical practice of facilitating learning and improving performance by creating, using, and managing appropriate technological processes and resources".

Computer programming Confidence: 68% Arrow up

Computer programming (often shortened to programming) is a process that leads from an original formulation of a computing problem to executable computer programs.

Programming involves activities such as analysis, developing understanding, generating algorithms, verification of requirements of algorithms including their correctness and resources consumption, and implementation (commonly referred to as coding) of algorithms in a target programming language.

Source code is written in one or more programming languages.

The purpose of programming is to find a sequence of instructions that will automate performing a specific task or solving a given problem.

The process of programming thus often requires expertise in many different subjects, including knowledge of the application domain, specialized algorithms, and formal logic.

Employment Confidence: 68% Arrow
