algorithm - Construct a Tree -


How do I build a tree, so that the inside and the preder are transverse? I'm just searching for a skilled algorithm.

A clear copy and paste:

< Strong> Question:
p_1 , p_2 ... p_n poster should be transverse and i_1 , i_2 ... i_n Inverters can be traversal from postorder traversal They are the root of the tree, p_n find this element in Insider Traversal, i_1 , i_2 ... < Code> i_k-1 say p_n i_k + 1 ... i_n . From Inner Travelers we find all the elements in the left subsection, i.e. i_1 , i_2 ... i_k-1 and in the correct subtree, i.e. i_k + 1 ... i_n .

element P_n (and element i_k == p_n ). Correct code in p_j in p_1 , p_2 ... p_j ... p_n-1 where p_j is an element in i_1 , i_2 . . i_k-1 . This is the root of the original tree's left subtitle. Split p_1 , p_2 ... p_j and p_j + 1 ... p_n-1 and i_1 , i_2 ... i_k-1 and < Code> i_k + 1 ... i_n . You now have two repeaters representing two sub-parts post orders and indoor traversal of the original post.

I have applied the algorithm once more, and it worked perfectly!

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
