顺着走一步碰到谁

运行下面这段程序：

class Node:
    def __init__(self, name):
        self.name = name
        self.next = None

def build(names):
    head = None
    for x in reversed(names):
        nd = Node(x)
        nd.next = head
        head = nd
    return head

head = build(["阿岚", "小满", "阿泰", "南风"])
print(head.next.name)
