How to get good at leetcode ?
To get good at Leetcode, you need to have a solid foundation in computer science concepts and algorithms, and be able to apply these concepts to solve problems efficiently and effectively. Here are some tips to help you improve your skills on Leetcode:
Start with the basics: Before diving into Leetcode problems, make sure you have a strong understanding of the fundamental concepts in computer science, such as data structures, algorithms, and time and space complexity analysis.
Practice, practice, practice: The best way to improve your skills on Leetcode is to solve as many problems as possible. Start with the easier problems and gradually work your way up to the harder ones. As you solve more problems, you will become more familiar with different problem-solving techniques and will be able to apply them to new and challenging problems.
Understand the problem statement: Before attempting to solve a problem, make sure you understand the problem statement and the constraints of the problem. This will help you come up with a plan to solve the problem and avoid wasting time on solutions that will not work.
Break down the problem into smaller subproblems: Many Leetcode problems can be solved by breaking them down into smaller subproblems and solving those subproblems individually. For example, if you are given a binary tree and you need to find the maximum path sum, you can first find the maximum path sum ending at the left child of the root node, then the maximum path sum ending at the right child of the root node, and finally combine these two values to find the maximum path sum of the entire tree.
Use the right data structure: Choosing the right data structure for a problem can greatly affect the efficiency of your solution. For example, if you need to store and access a large amount of data, using a hash table or a binary search tree may be more efficient than using an array or a linked list.
Optimize your solution: Once you have a working solution, try to optimize it further. This may involve reducing the time or space complexity of your solution, or finding a more elegant or efficient way to solve the problem.
Discuss and learn from others: Leetcode has a vibrant community of developers and computer science enthusiasts who are happy to help and share their knowledge. You can discuss problems and solutions on the Leetcode forum, or join a study group or a meetup where people discuss Leetcode problems and solutions. By learning from others and sharing your own solutions, you can gain new insights and perspectives on how to solve problems on Leetcode.
Take part in Leetcode contests: Leetcode offers regular coding contests where you can compete against other Leetcode users and solve a set of challenging problems in a limited amount of time. Participating in these contests can help you improve your problem-solving skills, learn from others, and have fun.
By following these tips and practicing regularly, you can improve your skills on Leetcode and become a more proficient and confident programmer.
