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!

Do check for all components (4 WA because of this)

AC in many go :)

very weak test cases

It seems everybody speaks of bipartite and dfs/bfs,but this problem can also be solved with unionfind sets Last edit: 20210830 07:11:41

Can be done with DFS. Bipartite is not necessary.

My solution is correct but it shows a compilation error :(

Simple bipartite problem solved with BFS. When stack empty, push unvisited nodes onto stack and continue.

@sa03195100 i guess out put will be :

Bipartite Using BFS

for c++ use vectors instead of arrays or declare global arrays with max size atleast 4000 (for nodes) , i was using max size 2005 keeping the 2000 limit in mind but it took more than 20 WA to figure that out :(
