I have solved the problem 10004 Bicolourable and gotten AC. I have submitted two different solutions and both of the solutions have gotten AC. However, there is a problem with the second solution. I have several test cases on which it doesn't work. It does get AC by the judge though. The test data for the problem is missing important test cases and I believe they should be added. Here is one test case which doesn't work on one of my solutions, but works on the other:
5
4
0 1
3 4
2 3
1 2
4
3
0 1
3 2
1 2
0
The answer to both of these is:
BICOLORABLE.
The solution that gets accepted by the judge gives
NOT BICOLORABLE.
for both of the test cases.
