My solution passed the first test case but showed TLE for 2nd sub test case.But I have already calculated prime factors for all numbers initially.
Link to ans:CodeChef: Practical coding for everyone
in each query you are calculating the cumulative again and again from l to r… better precompute your ans for every query from 0 to i… and then just print ans[r]-ans[l-1]…
and also in your first loop… i should go from 2 to MAX… not sqrt(MAX)… as there can be some prime integers between sqrt(MAX) and M which you didn’t considered in your answer.
