Prime visits(tle error)

why my code time limit error

#2

Hey @suhailrashidsalma its giving TLE because your code complexity is O(Range*Queries) which is not fast enough. So instead of solving each query in O(Range) time , you need to solve it in O(1) time.
You can do this by using a dp array which stores the number of primes up until that index ,i.e, dp[i] should store the number of primes from 2 to i. Using this dp array you can answer each query as dp[b]-dp[a].
