Hello! I have never thought I would write some post on Codeforces but now I am very terified.
Yesterday I tried to solve the problem 749D - Leaving Auction from Codeforces Round 388 (Div. 2).
The same code got TL when submitting with C++11 (23164369) but got AC with C++14 (23164381).
How do you think about what can be the reason?
I am sure this is because of cin. Read this.
