They want us to control binary trees or these prefix codes that they give us. All right, so let's go ahead and start with a here. All right? So we have a so four to code the letter A is going to be 11 So So we're gonna start from appear and we're gonna zero one. And then here we could go to zero or one, but we just want to go towards one. So let's do that. So we're gonna place eight out there now for E. So that's just zero. So we just have e here, then for tea, that's going to be one. And then we need to go zero and then one again. We're gonna go to the right place to be there and then, lastly, for us. So it's 10 Look it left and then again, zero. Then we place s down there. So this here would be the buying cherry tree for our coding scheme for a and you can see it is a binary or a prefix coding, because we really don't have any ambiguity since all of these are just leaps. Okay? No, let's go ahead and do be so it says we're going to start with a being just one. So we started here. We drove to the right one. And then that's gonna be a, uh then for E. That's going to be 01 That means we need start toe left to go there for zero. And then we'd go to the rate for one answer than we place E here. So for T, it says we're going to go zero and then one. And so then we place t right there and then s So we need to do 03 times will go left three times that one too. Three. And then we go to the right once and then that's going to be s. And then lastly for and we're gonna do 1234 left. So 123 four and then we go to the rate for one, and then that would be in. And then you can see that all of these air going to believe so makes sense that this is a prefix coding. I got a little bit better for my box and then for our last one over here. Okay, so it says a we need to go to the right because of one. And then we need to go to the left for zero. And then we would go to the right again for one, and then we would go to the left again for zero. And so that's going to be a now he is just zero. So that means we just go to the love you put zero there and then we place E down there and then t well, that means we go to the right twice. We go one and then want to get and then for s, we're gonna have one. So we go to the rate zero, go to the left, and then we go to the right for one, and then we go to the right one more time. So that would be yes. And then for in is gonna be one zero. And then we need to go to the left again for zero and then to the rate for it. And then lastly for I So we go to the right once they were going to go left three times so one too, so that we need to put an extra branch here and then we go to the rate one time, and then that's going to be I. Then again, you can see that all of these are just leaves, so we really don't have any ambiguity for any of us, and so this would be are buying territory for that coating?
