What are interesting problems that requires no specific algorithms?
By Hamada14, history, 8 years ago, In English

I was interested in practising more on problems Div2 C and Div2 D, But such problems where they don't depend on any specific algorithms: dp, binary search, graph, tree,....etc rather on problem solving skills where the difficulty is in the apprehending the solution itself. also problems which depend on creating certain permutations or matrices that specifies certain conditions.

any resources related will be welcomed too. If you can recommend any please, Thanks a lot :D

Most of the easy problems from tags like "constructive algorithms", "implementation", "brute force" etc. could be what you're looking for. Are you sure you checked this?

      There is a binary string s of ones and zeroes of length 1000 , you should find the string by asking at most 1024 questions.
      In each question, you can ask if a certain string occurs as a substring of s or not.

If I recall correctly IOI'13 Art Classroom does not require a "specific algorithm". It's kind of in the vein of classification problems like machine learning.
