Advanced C/C++/Pypy3 Data Structure Challenges

I'm seeking a competitive programmer to tackle 4 advanced-level programming questions I have. The questions will primarily focus on data structure implementation. The programming languages for this project are C, C++, or Pypy3.

Key Requirements:
- Proficiency in C, C++, or Pypy3
- Advanced understanding of data structures
- Strong problem-solving skills
- Experience with algorithm optimization
- Ability to pass all test cases for full compensation per question

Please note, the focus of these questions will primarily be on data structure implementation. The ability to optimally use arrays, lists, trees, graphs, hash tables, and heaps will be crucial.

Question 1 : Level is easy : If the solution is correct : Rs. 1000
Question 2 : Level is Medium : If the solution is correct : Rs. 2000
Question 3 / Question 4 : Level is Medium : If the solution is correct: Rs. 4000 (If you can able to solve both the questions then you will get: Rs. 8000)
If you can able to solve all the problems you will get : Rs (1000 + 2000 + 4000 + 4000) = Rs. 11000
