Currently I am trying to solve more than 5 problems in day but I can't find any problems that will help me to achieve a great experience. So, I wish you will give your favorite problem(which is typically great for himself/herself) so that I can solve it and achieve a great foundation.

I am a programmer and a student in grade 6. I want to start Competitive Programming (CP), but I struggle to solve problems involving Binary Trees, Graphs, Dynamic Programming (DP), etc. However, I am very enthusiastic about learning CP.

Currently, I am learning Backtracking, and I feel stuck on how to approach problems related to them. If anyone knows of any Backtracking tutorials or blogs, I would greatly appreciate it if you could share them with me.

Right now, I feel upset because I feel like I am wasting my time, which I could use more productively. If anyone could guide or help me with this, I would be truly grateful and thankful to them.
