Whenever you practice a subject, be sure to try to solve the average problems of this subject. Once you are comfortable with the subject, try to solve difficult problems of the same subject. Try easy problems only if you want to know more about the basics.
No one is going to pose the problems of Leetcode Euille in the interview.

Do not only solve problems for the thermal card in your profile or the Leetcode badges. If you try to solve the problem of the day, it is good but do not copy / paste from the solutions section. You would not read this article if you are able to solve Potd every day.
You just cheat with yourself.

Suppose you started learning a new subject, first make sure you know the basics of the subject, then move on to resolution problems.
What problem to choose?
Always choose a problem with a good acceptance rate at first. This will help you gain confidence in this subject.

You see the problem and you just started thinking about the solution. An approach has clicked on your mind, you started writing the code. STOP You hurt.
When an approach has clicked on your mind, first make sure you dry your approach on certain test cases. You must always use a notebook to view the tree, graphic and recursion as subjects. If everything went well, start writing code.

If you have just solved a problem or if you are unable to solve a problem, you can use Similar questions functionality. You must always try to solve more and more similar problems because each problem has something different, it will give Boost your confidence and
Yahooooo! You have solved another problem.

Okay, I clean again here, do not copy / paste a solution only for resolution. If you have solved a problem, make sure you have checked the Solutions tab and see how the others have solved it. It is very beneficial for your knowledge, because often, a problem can be addressed from several directions and subjects.
Remember that if you are right, that does not mean that others are wrong.

You do so much hard work, learn and practice all subjects but For what? You have to erase interviews, right? So who will try them?
Always try live contests to check your progress. When you have practiced problems, you knew the subjects, but here it is a simulation to a real maintenance. Do not think of notation.
Try it and do your best, no one will judge you.
