lua单链表实现

    List = {}

    --创建一个节点
    function List.new(val)
        return {pnext = nil, value = val}
    end

    --往一个节点后添加一个节点
    function List.addNode(nodeParent, nodeChild)
        nodeChild.pnext = nodeParent.pnext
        nodeParent.pnext = nodeChild
        return nodeChild
    end

    --输出链表
    function List.print(list)
        while list do
            print(list.value)
            list = list.pnext
        end
    end

    --实现尾部插入
    pHead = List.new()
    local node = pHead

    for i=,  do
        node = List.addNode(node, List.new(i))
    end

    List.print(pHead)

    --实现头部插入
    pHead = List.new()

    for i=,  do
        List.addNode(pHead, List.new(i))
    end

    List.print(pHead)
