Problem: Filip (https://open.kattis.com/problems/filip)
Java String is immutable so when you need to do a lot of String manipulation, it's more efficient to use the StringBuilder class instead. You can also do more like reversing the string, which I demonstrated in this video.
You can find more info about StringBuilder here: https://download.java.net/java/early_...
By the way, in the video I used the constructor to build a StringBuilder, e.g.
StringBuilder s = new StringBuilder("Hello");
but you can also do
StringBuilder s;
s.append("Hello");
which may be faster to write.
