Just wanted to get some clarification, for the problem D of today's contest (Codeforces Round 891 (Div. 3)). I got this weird error (runtime error) in the following submissions (using java):

• https://codeforces.net/contest/1857/submission/217678309

When I submitted equivalent code using long, it worked (using java): - https://codeforces.net/contest/1857/submission/217686813

Using int, cpp code worked though: - https://codeforces.net/contest/1857/submission/217741962

Anyone has any idea what might have happened? I would really appreciate the help. Thanks in advance.
