Can someone tell me how to count triangles in a graph in nsqrtn
In nsqrtn ?
i don’t think it is possible to do it nsqrtn , the fastest i know is using Strassen’s matrix multiplication which does it in O(n^2.8)
and guess what that too is inefficient in practical purposes because it takes large amount of extra memory in recursion.
So conventional O(n^3) is best i know so far
PS :If you are able to find an algo which works in nsqrtn please do tell me 
Link to the problem?
Yeah without it we should wait for at least 10 days before replying ( because a ongoing contest may last for 10 days or someone else might report meanwhile)

How about in undirected graph
