On my PC it runs perfectly correct, the output is exactly the same(i have checked it using equals method so a mistake is impossible) but i get WA1 somehow. If somebody has an idea, please write it here.
BTW I know that the first test is the sample test because a simple program that prints sample output gets WA2.

PS here is my code if someone's interested: https://pastebin.com/SYiQTbMt

Do you think test case number one is the sample?
