search - Put into an array the deepest path of a BST (recursive) -

-

I am trying to insert the most deep path to BST using a recursive algorithm for an array, and I have many difficulties Is facing ... because the only thing I get is the size of the longest path (height equal to), and I can not think about the height of BST in the array ...

Can someone help me ???

Thank you in advance ...

Sorry ... I did not fully expose the problem ... This is the only thing that I have signed this algorithm: / P>

// 3 nodes of each node are: value, left and right

private int [] the deepest path (node ​​route) {...}

( I can use the aux methods ....)

as a tool for rebuilding Try to use the nodes the deepest path

you Programming which may be an issue as it is that you have no way of storing the actual nodes you cross the tree. What you need "to remember" is a way that the leaf you have taken on the path is considered to be the deepest.

If your BST is displayed in the nodes, then you may want to consider that in each child, store a reference for your parents, in this way, when you reach deeper leaf, then you (Note: Path will be in reverse order) such as: 

  if (isDeepest (node)) {// Once you find the deepest node. .. back to the reconstruction text (node); // ... reconstruct the path that took you there ... reconstruction is a method that takes a node (deep leaf) as an argument and gives the array in the root from that node is. Private Array Reconstruction Path (node ​​node) {Arrays deep path = new array (); While (node.parent! = Node) {// until you reach the root, which will be the deepestPath.add (node); // array node = node. Add node at the end of the point; // Go to the parents of the node from one level} deepestPath.reverse (); // Cancel the order so that it can be root- & gt; Leaf Returns The Deepest Path; }

If you do not want to use nodes, there are other ways to do this, but this is an easy way to visualize the problem in your head.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
