If you have WA on test #3 or on test #1 or on test #2 you must use DP! Else if you have WA on test #4 you must use unsigned int or int 64 or long. If you have WA on test #8 you must change start and finish points ( 6-2 and 2-6 is equal ) !^_^!

Thanks a lot for WA 8.I got AC.^^

If you have WA8 and use Binary Search - check that it work properly, i.e. return far station instead of nearest
