Good luck

Try ios::sync_with_stdio(false); and be happy

Thanks so much!!! Exact same thing for me, and I would have never figured it out :)

I didn't find the "ios::sync_with_stdio(false);" hint to help though... stayed too slow.

Thanks!
I got AC, but in 1.968 time using cin and cout. I spend o lot of time for optimization.
Replacement cin to scanf gave 0.359 time in total :)

try to use gets()+strtok()+atoi(), you will get better results ;)

First time I used ios_base::sync_with_stdio(false) but many times I got TL on test 4, but changing cin and cout to the scanf and printf respectively, I got AC.
