Hi codeforces.
I tried to solve this problem and for my interest I wrote the same problem in Java and after this in C++.
And this are the results :
Java = 1092ms;
C++ = 421ms;
So C++ is ~ 2,5 faster than Java, so this difference can make you win or lose a problem during the contest.
Maybe I make something wrong in Java and Java is faster than I think? So I have few day since I start to solve in Java ,hope to receive from you good hints for making my Java program run faster.
I didn't make any changes in C++ program, just rewrite the same program from Java in C++
