15 Coding Challenges Platforms to Improve Your Programming Skills

The computer has become a powerful yet cost effective means to take over many fields of works that are rather mechanical or formula based. In fact, computers can deliver better performances in these areas compared to human employees. There is an extra investment for the maintenance but even including that, the total cost is much cheaper considering the quality output.

The future inevitably belongs to the machines and to the people who can program/engineer them to act to our needs. Hence, computer programming is a crucial skill for this generation and the next.

You will know about programming from a lot of sources but just knowing isn’t good enough. It is like maths. You have to practice and find out new imaginative ways of tackling problems.

For this purpose, there are a lot of coding challenges that you can take to help train your brain and become a better programmer.

There are a lot of coding challenges that you can find online. Here we have shortlisted some of the better ones so you can save time by ignoring the searching and going straight into solving.

So without further hindrance, here are the best 15 Coding Challenges to Improve Your Programming Skills:
