I have a method I created which is a custom indexOf(). This code seems ugly to me so I was wondering if anyone could recommend a cleaner and perhaps faster implementation of my method
method:
public static int myIndexOf(char[] str, char[] substr, int index) {
if (str == null) {

The runtime of the 1st solution you posted is not O(n2).
You are just traversing the string twice, which makes it O(2n) => O(n).
I have the following code for connect_four game. I have written a random computer player. How can I make it smarter without too much code? Are there some tricky methods I can use?

As you've seen, I've experimented a bit. Sorry for jumping the gun and going ahead like this, I hope not too much damage was done. I've given this lots of thought lately, and I come to a conclusion that's radically disagreeing with the idea.

Are you sure you need the precision of double for scoring? I only ask because I recently had reason to down-convert a system to float because it had many millions of scorable items and the memory saving ended up being significant.

If you are using GCC, we can use the typeof()(C99) keyword to get rid of one of the arguments. Also, add a do-while so the macro to be used in contexts where it would otherwise be problematic.

You could also use an exclusi...
