BUGLIFE - A Bug’s Life
Professor Hopper is researching the sexual behavior of a rare species of bugs. He assumes that
they feature two different genders and that they only interact with bugs of the opposite gender. In
his experiment, individual bugs and their interactions were easy to identify, because numbers were
printed on their backs.
Given a list of bug interactions, decide whether the experiment supports his assumption of two
genders with no homosexual bugs or if it contains some bug interactions that falsify it.
Input
The first line of the input contains the number of scenarios. Each scenario starts with one line giving the number of bugs (at least one, and up to 2000) and the number of interactions (up to 1000000) separated by a single space. In the following lines, each interaction is given in the form of two distinct bug numbers separated by a single space. Bugs are numbered consecutively starting from one.
Output
The output for every scenario is a line containing “Scenario #i:”, where i is the number of the scenario starting at 1, followed by one line saying either “No suspicious bugs found!” if the experiment is consistent with his assumption about the bugs’ sexual behavior, or “Suspicious bugs found!” if Professor Hopper’s assumption is definitely wrong.
Example
Input: 2 3 3 1 2 2 3 1 3 4 2 1 2 3 4 Output: Scenario #1: Suspicious bugs found! Scenario #2: No suspicious bugs found!

What is AC, about which people are talking about?. I'm new to coding so don't know about it. |

For people who don't understand. This thread is not for boasting about getting AC in one go.

use bipartite and be aware of disconnected graph Last edit: 2018-09-27 22:49:22 |

"Bugs are numbered consecutively starting from one."

Be Careful, there can be disconnected graph also! |
