 You need to return in the card. Yeah, that's exactly correct. So to answer your thing, you can put an L in the card, but if you put an L, basically this is giving an option to exit early from the program, you need to return here. So you need to put an L. That's pretty much it. Okay, now this is going to get slightly more difficult. Is this the correct way of writing enums in switch? Easy to answer is yes and no. You can assign a low value to the enum. I'll say yes because it's an enum of tuples. At least that's how I understand it. So, I'll give you a book about the question, but this is not right. Okay, let's see it on the playground. Let's see what error it is, right? What happened? So when you're assigning values to an enum, it needs to confirm to this protocol equally. Which means you can only assign things like, so you cannot have an enum of tuples. You can have enums of eight teacher, but if all you know that, you can have like one, two, three, four, whatever, you can have an enum of string, you can have an enum of this. Yeah, so unless the tuple implements the equatable protocol then should be okay, right? Yeah. Understand? Okay, now. Now, what is the output of this? You need to raise your hand. I cannot answer. You need to raise your hand and then I'm going to random the answer. Anyone else? Anyone? Give me a try. No? Where? See. Please. You need to give an error. Yeah, compile error. Compile error. Why? Because it's stuck to the value type and you can't define a static problem. I'll give you the code, but it's not going to work that way. It cannot access the static variable. Oh, with the like instance name? Yeah. Oh, okay. So it is not static, it can access it. You didn't say it can programmable and talk free of language. That would work. Okay, let's see. Let's play around. If I remove this. No, this is. Let's wait for it. Because you don't have a default unique method, so that's why it's taking in the same order. Okay, so both of you can give me your email ID. I will email you. You need to get the free book before 20th of this month. Just like you have for seven days. And then just use the. That's it from me. So yeah, I'm sure I tell anyone that I need to share their new app. So what is this? It's programmable and talk free of language that work. I think it's a static. If I say it's free, it's programmable and talk free of language that work. Just thought that I should say our word. Because I heard that some people thought we were a law firm. So anyway.
