So the allowed values for m sub l 0 are going to be negative l, all the way up to 0, l and then up to positive l.

所以m小标l的可能值,是从负l，一直到，然后到正。

So, our next level up that we can go is going to be the n equals 2 energy level, but we also have an l and an m value, 0 so our lowest l is going to be a there.

所以下一个能量,是n等于2的能级，但我们还有l和m的值，所以我们最低的l等于。

It says, right. If j is-- well it says until j is at the less than the length of l-- it says, if min value is bigger than the thing I'm looking at I'm going to do something, all right?

只要j比长度l小,如果MinVal比我要找到元素大，我就要做些什么了,我们来遍历？

So finally, if we talk about our last example of when n is going to be equal 2, l -1 and then minus 1 for m.

最后我们要讲的,这个例子，是n等于2时，等于1，we，can，have，2，，1，for，l,而m等于。
