我还记得要,在箭头尾部打个叉,然后让加法完结了。
And that's like kind of hoping that the element you're searching for is the first in the list and the last in the list. Maybe.
也就是希望要找的元素,在数组的头部或者尾部,情况可能是这样的。
Let's go the other direction. And yes, I guess I'd better say s not 2, or we're going to get an error here. Again, in twenty-three checks.
这里我得说不能是2,否则要报错了,再一次,调用了23次,在这个例子里,它从尾部开始。
