[Help] Range = sqrt(sum) By YoussefObama, 17 months ago, How did people solve this problem based on the fact that max(a_1, a_2, ..., a_n) — min(a_1, a_2, ..., a_n) = x where a_1 + a_2 + ... + a_n = x^2 how is this correct?
Hi,I'm trying to solve this problem.It asks for point update and range query where the query is sum of distinct numbers in a given range. Problem Link Is this type of problem solvable by normal segment tree or do we need any kind of persistent data structure to do this?? I don't ...
