which primes are best for hashing a graph? like two tree is isomorpic? then we need to hash the graph..need some prime. which are best for it. thank you :)

You can find here.
thanks vai..i think for these problem we need higher prime, cause nodes can be up to 10^5 ..i am not sure.
use unordered_map
i think it'll work for your work or u can google for the primes over 1e6 and find your power and mod... :)
In this problem, i saw that everyone use higher prime. In lower prime they get Wa.. They use 10^10 up primes.
