我们知道0不能算作一个节点,如果我确实把零点画成了0,那正确的答案应该是下面的那个。
We know that the zero does not count as a node, if per se I actually had managed to hit zero in drawing that, the correct answer would be the bottom one there.
我把你算作我的一个朋友。
然而,虽然像上一条那样,但是我还是一直想要一个跑车。所以把这个算作一个打算。
However, while doing that, I have always wanted a muscle car. So, will contemplate that as well.
I'm glad to hear that no one counted this r equal zero as a node.
我很高兴没听到有人把r等于0这处也算作是一个节点。
