I was solving the [problem:https://mirror.codeforces.com/contest/1942/problem/H], but some strange things happened.
At the beginning, I got a RE in testcase 70, I thought it may be some memory problem in my code, so I use the variable is_special to locate it. But it doesn't work, so I tried to sumbit the same code in another language, it got accepted!
You may think that there must be some undefined behaviors in my code, but actually I tried to hack at the front of the code, it got different verdicts too!
And the strangest thing is that the flag is_special is about the data input, theoretically it shouldn't be different even though with different language. It really confused me, can someone tell me what happened?
