100求一个算法?DOS时代画了一个表参考
现有一个树状数据存在数据库中.
编码 名称
001 a
001001 b
001002 c
001003 d
001003001 e
001003002 f
001004 g
001005 h
001006 i
001006001 j
001006001001 k
001006001002 l
001006002 m
001001是001的子级,以此类推.如001是所有级的父级.
现需求如下:将数据形成表格的算法.
---------------------------------------------|------------|
类别 | 数量 |
------|--------------------------------------|------------|
| 001001 | 1 |
|--------------------------------------|------------|
| 001002 | 2 |
|----------|---------------------------|------------|
| | 001003001 | 1 |
| |---------------------------|------------|
| 001003 | 001003002 | 5 |
| |---------------------------|------------|
| | 合 计 | 6 |
|----------|---------------------------|------------|
| 001004 | 5 |
|--------------------------------------|------------|
001 | 001005 | 7 |
|---------|-------------|--------------|------------|
| | | 001006001001 | 4 |
| | |--------------|------------|
| | 001006001 | 001006001002 | 2 |
| | |--------------|------------|
| 001006 | | 合计 | 6 |
| |-------------|--------------|------------|
| | 001006002 | 4 |
| |----------------------------|------------|
| | 合 计 | 10 |
|---------|----------------------------|------------|
| 合 计 | 31 |
------|--------------------------------------|------------|
第一个级别有一个合计.
怎样才能让表格成这种样子.表格具有合并的功能(类似电子表格).
[解决办法]
如果001003是001003001和001003002的父项，那个001003本身是没有值的吧
那么只要是父项 都是没有值的。是这样吗？
[解决办法]
好像很复杂啊，顶起来
[解决办法]
顶，学习中
[解决办法]
很典型的递归
[解决办法]
就生成一棵树,再递归生成表格吧.
[解决办法]
关注LZ，友情UP一下
[解决办法]
更好的办法? 我觉得这玩意最好就是用递归了.
generate(currentnode)
{
if (currentnode.haschild)
generate(currendnode,child)
else
print "XXxXX "
}
大概如此吧.
[解决办法]
类似MRP里的BOM展阶.
[解决办法]
你这个是什么意思??如果你做个无限树跟统计树节点数目的话..我做过!!
