I have written the code to solve 1609C - Сложный анализ рынка problem, but it gives TLE. I think the complexity of my soln. is O(n*log(log(n) because of Seive rest of the work i have done in linear time. My approach is as follows:

Suppose arr[i] is prime I have calculated the number of chains of 1 on left of arr[i] and similarly on right of arr[i]. Then i have used sum+=onesLeft[i]+onesRight[i]+onesLeft[i]*onesRight[i]; to get the answer.

Here is my submission ----> https://mirror.codeforces.com/contest/1609/submission/160055418. Please tell where I am wrong in calculating the time complexity? Thanks in advance.
