Response to Research in Easy Writer

Research

Here come the fun part. While it's usually quite a burden, I always get excited to do the research paper every year. And the cycle is usually something like this: arrive at library, painfully search for books relevant to my topic, lazily write down notes, leave, forget everything, come back the next day, repeat. That is such a precise cycle I could write code for it.

public String research(String topic)
{
    if (topic.length() > Integer.MAX_VALUE)
        return "";
    int x = (int)(Math.random() * topic.length());
    return topic + research(topic.substring(x) + topic.substring(0, x) + topic.substring(x);
}

As anyone that knows what this does could tell you it's a nightmarish process filled with recursion and heaps of trouble. For anyone that can't read this, well it already looks like a nightmare to you, doesn't it? However, this guide instills confidence in me that yes, I can do it this time. And ideally, the more I do it the better I should get, right? Regardless, I've been quite restricted in what I could write about in the past. I hope that isn't going to be the case anymore.

For the curious, my first run of this code with the input "RERESEARCH" with a more reasonable value in the base case led to some interesting results. Try it with 1000000. It's hypnotic.
