Forehead, did very bad.
Mainly scared on an exam, thus holding the title played violent state of mind to do, it can be said to have failed miserably. But violence also will not play, to test the mentality of half of the bombing, and gave up.
One hour before the demodulation error violence T1 (waste), then adjust violence T3, T2 and finally violence, but T2 Yes.
30 + 10 + 20. T3 violence is 50, but I am only 20
T1 The DP is already figured it out, but have been left less than ten minutes, it did not turn in code.
T2 disguised see graph theory was not any violence nor write, just write a wrong solution to give up.
Inclusion-exclusion principle T3 or did not expect, is unexpected.
After the exam or not to abandon it. Just should not do it, we can not give up.
