hahah~~~

The first time I used FlowerTree to solve this problem but got TLE #4.

Than I write it again by another methods and got TLE #3....

I thought it again and again~~

weeks later, I got AC~~~~

In your log written:
... 1098 1/1, 1099 1/2, 1100 1/9,...
This mean that you submited this problem 2 times and on one of them you got AC, but in your post submit #1 - TLE, submit #2 - TLE, ... sumbit #? - AC. ? is a number grather than 2. ...strange...  :))))

Sorry, I solved this problem with my friend. I just submited my source by my friend's ID.

I don't love Flower Tree.

But it seem that there isn't any other way to AC this problem but Flower Tree...

Anyway, I will try...

Many Thanks
