Given a graph with n nodes and m edges . n ≤ 100,000 and m ≤ 1,000,000 . We have to find any odd cycle.
How to solve this problem ? I tried in naive way. I just stored the nodes when I get any cycle of odd length . But it will obviously TLE.

Give a directed graph and you have to output one of the odd cycles
