Today everyone learns to code as it a basic requirement in todays digital era.
Beginners in this field listens about competitive coding and start without any pre-knowledge.
Leetcode is one of the best platform for coding whether you are a beginner or pro.
but for beginners, they don't know where to start or how can they become better in coding.
At first i recommend to have a basic knowledge of cpp,java or python. these are the programming languages that are best for coding.Then once you learnt a language try to solve easy questions on leetcode and HackerRank.
first try to find a logic even if you dont know how to code it.it will improve your logical skills and then eventually you yourself will be able to code the answer.It is a great journey to learn coding and once you get a hang of it you will just love it.
