Please have a look at the following two submissions of 1582E - Pchelyonok and Segments:

1. 138848779
2. 138849288

The first submission gave RTE on test 8. But just by replacing ll with int, it passed test 8. (Though it failed on test 9 due to integer overflow). Can anyone tell why is the first submission giving RTE? Any help is appreciated.

C++ is not my primary language, so I may be making some silly errors.
