Here is a list of the 8 best programming skills for developers today.These websites provide exercises, challenges to practice code skills, interviews etc. These lists are arranged in order from easy to difficult:
Coderbyte offers more than 200 challenges that you can solve directly in the online editor in 10 different languages.This website also provides solutions for over 800,000 solutions from programmers around the world.
Codewars provide a huge number of challenges that are devised by the very inner community.Like Coderbyte, Codewars also has an online editor with over 20 different programming languages.You can also discuss each challenge as well as solutions.Through it, you can earn points and increase your rank.
CodeFights, in addition to presenting challenges to programmers, also has a dedicated forum for discussion, and they also have a feature called Company Bots, where you’ll be able to code a bot. Programmed by programmers coming from companies like Uber, Dropbox, and Quora.
Unlike the above sites, Codingame instead of simply solving the problem and giving output, the programmer will participate as a quest in the game.This combination of learning and play makes the challenges more enjoyable.Graphics / UI of the game is also very beautiful and eye-catching.So this is an ideal place for new programmers to develop their skills.
TopCoder is one of the first programming platforms to be set up, where you will experience algorithmic challenges.TopCoder has a Single Round Matches system that runs several times a month where you will compete with thousands of other programmers, and the prizes of these contests are all very attractive.
HackerRank focuses mainly on computer science, so the challenges are mainly in the areas of algorithms, mathematics, SQL, Algorithms, Mathematics, SQL, Functional Programming, AI.
LeetCode has a huge collection of the latest algorithm challenges.Their topics require knowledge of data structures such as binary trees, heaps, linked lists … so their problems are often more difficult than common ground, but they are also very interesting and compelling.In addition, they also have theMock Interviewprogram that simulates job interviews or monthly code contests.
GeeksforGeeks has a wealth of collections of articles, solutions for algorithms and data structures, as well as challenging and compelling mathematical problems.If you are planning to attend an interview, this is a great place to study and prepare.
