Please don't write code like that. Firstly, it's long and bloated, and 
runs at the speed of Python, not C. Second, it runs at the speed of 
SLLLLOOOOOOOOOOWWWW Python, not fast Python, due to being an O(N**2) 
algorithm.

If you don't know what O(N**2) means, you should read this for an 
introduction:
