Other than more practice, code style also matters in solving implementation problems. Knowing the full solution with all the conditions and then implementing it will be more helpful rather than figuring out various conditions and scenarios while implementing. One thing you can do is to break your solution into multiple parts and implement them separately, maybe use distinct functions for each part. Then it will be more readable and will help you to understand the purpose of each function, making it easier to identify and fix any bugs.
