Yes, it is beneficial to do pen and paper solving for coding problems. Here are some reasons why:

• Improves problem-solving skills: When you solve problems on paper, you have to think through the problem in detail and come up with a plan to solve it. This can help you improve your problem-solving skills.
• Helps to understand algorithms and data structures: When you solve problems on paper, you manually simulate the algorithms and data structures you are using. This can help you gain a better understanding of how they work and how to use them effectively.
• Reduces reliance on code: When you solve problems on paper, you are forced to think through the problem without relying on your code. This can help you become a better problem solver overall and reduce your reliance on code to solve problems.
• Improves debugging skills: When you solve problems on paper, you have to manually trace through your solution to find any errors. This can help improve your debugging skills and make you better at finding and fixing bugs in your code.

Overall, doing pen and paper solving for coding problems can be a great way to improve your problem-solving skills and become a better programmer. It also allows you to solve problems without the distractions and complexities of a computer, which can help you focus on the problem at hand.
