t In the b even case, again I'm going to let t of b be the number of steps I want to go through.

如果b为偶数，那么我还是要用,来代表解决这个问题需要的步骤数。

On the next step though, this, we get substituted by that. Right, on the next step, I'm back in the even case, it's going to take six more steps, plus t of b minus 1. Oops, sorry about that, over 2.

这一步就是偶数了，这一步会让我们得到，6+t这样的结果，因为b-1现在是偶数了,别忽略这里的细节。
