You may hardcode all highly composite numbers and then answer every query in log time using binary search)
I don't know about highly composite numbers . can you give me some link about this ?
Some link — it is essentially set of all possible answers :)
thanks :)
You can find the 1st 70 prime numbers and then for each 'n', loop through these numbers in the following way-
Start from i=0, ans=1. ans=ans*prime[i] as long as ans<=n. i++.
if ans*prime[i]>n, reset i=0 and repeat step 1 until its no longer possible. Maintain a hash of these primes you are using for frequency.
edit: we can pre calculate product of these primes in an array, and for each test case, we do a few binary searches. Why so many downvotes?
