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!

be careful of the formatting, got WA for forgetting to include colons.

very easy just use dfs :)

TLE by cin/cout .. AC by printf/scanf

was printing
No Suspicious bugs found!
2015-06-25 10:49:36 who cares
HMM BFS I LIKE YOU =D =D
DFS still wants to know about your depth :(

My first graph problem! Feeling good :)
Studied geeksforgeek article on bipartite graph and then incorporated that concept for this question.
After little struggle, finally green light!

sort of graph coloring with 2 colors

easy one....BFS is sufficient :)
