Tags: algorithm, data structure, binary tree traversal Rotating a 90-degree print binary tree in a counter-clockwise manner is a special medium-order traversal algorithm. Rotate 90 degrees counter-clockwise The implementation is also very simple, similar to the middle-order traversal algorithm. Before the output node value, use a special mark to record the layers and output appropriate spaces. Code: Void prtbtree (bitnode * P, int cur

1. Description of the problem189. Rotate ArrayRotate an array of n elements to the right by K steps.For example, with n = 7 and k = 3, the array [1,2,3,4,5,6,7] was rotated to [5,6,7,1,2,3,4].Note:Try to come up as many solutions as can, there is at least 3 different ways to solve this problem.Hint:Could do it in-place with O (1) extra space?Related Problem:reverse Words in a String IITags:arraySimilar problems: (m)

Copy CodeThe code is as follows: /** * Modify a picture to flip the specified degree * * @param string $filename file name (including file path) * @param float $degrees degrees of rotation * @return Boolean */ function Flip ($filename, $src, $degrees = 90) { Reading pictures $data = @getimagesize ($filename); if ($data ==false) return false; Reading old pictures Switch ($data [2]) { Case 1: $src _f = imagecreatefromgif ($filename); Case 2: $src _f = Imagecreatefromjpeg ($filename); Case 3: $src

Use vector dot product to rotate the model around the center How to rotate a model around the center in a 3D space? This problem sounds easy, but after my practice, I found it quite difficult. In the initial stages of studying OpenGL and DirectX, I believe this problem still hurts everyone's brains. How can this function be implemented? I think you may need to go back and review our high school knowledge. T

Label: style blog color Io for SP Div on Log Given a list, rotate the list to the rightKPlaces, whereKIs non-negative. For example:Given1-> 2-> 3-> 4-> 5-> nullAndK=2,Return4-> 5-> 1-> 2-> 3-> null. Rotate the linked list: Find the length of the linked list, and determine K, K = K % Len; then follow the last-slow idea, let the P pointer go K steps, and then start Q, when P-> next is null, Q is the rot

Rotate ImageYou are given an N x n 2D matrix representing an image.Rotate the image by 90 degrees (clockwise ).Follow up:Cocould you do this in-place? Solution 1: We can treat it as multiple nested loops and add a ring. From Outer Ring to inner ring. To facilitate the processing of various subscripts, we define top, bottom, left, and right to limit the upper and lower boundary of the ring. 1. Make TMP = upper boundary 2. The top is equal to the left

For the original question on CC, remember that the time complexity O (N ^ 2) and space O (1 ). Algorithm ideas: Each transpose is mapped to four points of the ring. The coordinates of these four points are related to N. The coordinate relationships of the fo

Given a list, rotate the list to the rightKPlaces, whereKIs non-negative. For example:Given1->2->3->4->5->NULLAndK=2,Return4->5->1->2->3->NULL. The main purpose of this question is to understand the meaning of rotate. This meaning is a bit similar to the right shift of the binary number, but here the number of the complement high is the number of the right shift Personal thoughts: 1. Calculate the length o

rotation of the sprite is still in the upper left corner, so it rotates when it is on that great circle;So, what if we need a bitmap or a sprite that doesn't rotate or zoom to its content center?The answer is: combine the two above to form a new layer, the principle is very simple, as follows:The code is this:DOCTYPE HTML>HTMLLang= "en">Head> MetaCharSet= "UTF-8"> title>Rotateandscaletitle>Head>Body> DivID= "Mylegend">Div> Scriptsrc=".. /

method One: 1, first open PS, click "File"-"open" 2, open the picture you want to rotate 3, then select "Image"-"image rotation", you can see the rotation of several methods, there are 90 degrees, 180 degrees, such as several commonly used rotation, there are horizontal flip and vertical flip, such as rotating mode The former rotation is based on the image center, the latter rotation is based on horizontal and vertical lines, so you can see th
