Problem is relatively simple, but do very bad.
T1 is a number of combinations to find the law stupid fast power, a small opening array (wrong data range)
T2 topic guarantee Unicom did not see, hack out a positive solution.
T3 is also very stupid, but upset, thinking is not very clear cause lost 50 points.
I can only say, look this is a small problem to a large emphasis on the issue did not change overnight.
Finally there is an examination can take less than an hour think of three positive solutions, the results have not actually a A.
Recently things more, the mood is also more complex, LCT bottom very tough topic. . .
So what do not want to say.
Then go for it, maybe there is hope yet.
Say no good.
