Topic:Given a binary tree, return the zigzag level order traversal of its nodes ' values. (ie, from left-to-right, then right-to-left for the next level and alternate between).For example:Given binary Tree {3,9,20,#,#,15,7} , 3 / 9 / 7Return its zigzag level order traversal as:[ 3], [20,9], [15,7]]Solving:This question is actually similar to the sequence traversal of the two-fork tree, just on this basis, with a left and right direction.

2. How to crop images in blocks?
Because the image we selected may not be completely divided into the required number of parts. For example, we set the horizontal value to 3, but the image width is not a multiple of 3, in this way, we need to crop the image to get the most appropriate size;
1 var validWidth = img[0].width - img[0].width % xCount;2 var validHeight = img[0].height - img[0].height % yCount;
Now we need to calculate what kind of image should be drawn in each squar

DescriptionThe multiplication puzzle is played with a row of cards, each containing a single positive integer. during the move player takes one card out of the row and scores the number of points equal to the product of the number on the card taken and the numbers on the cards on the left and on right of it. it is not allowed to take out the first and the last card in the row. after the final move, only two cards are left in the row.
The goal is to t

The detection algorithm requires you to think about it by yourself, because the position of the four points after the image is rotated has changed. It is a small difficulty to judge whether there is a corner of the image in the clicked place, you can zoom in, zoom out, move, and rotate the image in ondraw using matrix. If the size of the final generated image is different from that of the preview image, the image is multiplied by a ratio.
The general idea is that the Code is not convenie

By sharing pojo objects in a cluster, the terracotta container makes pojo no longer limited to the SNA (share nothing impact ect) architecture, and supports the cluster mode transparently, this is the last piece of puzzle for pojo development models.
In fact, it is a central cache server. After adding the terracotta parameter to the application startup command, classloader modifies bytecode In the JVM-level way according to the configuration file. You
tells you another scene: It prints 60000. Why does it perform incremental operations on minutes so frequently?
The problem is that the Boolean expression (MS % 601000 = 0 ). You may think this expression is equivalent to (MS % 60000 = 0), but they are not equivalent. The remainder and multiplication operators have the same priority [JLS 15.17], so the expression Ms % 601000 is equivalent to (MS % 60) * 1000. If (MS % 60) is equal to 0, this expression is equal to 0, so the loop performs increme

Nan has other amazing features. For any floating point operation, if one or more of its operands is Nan, the result is Nan. This rule is very reasonable, but it has strange results. For example, the following program prints false:
class Test { public static void main(String[] args) { double i = 0.0 / 0.0; System.out.println(i - i == 0); }}
The principle behind this Nan calculation rule is that once a computation produces Nan, it will be damaged, and no further computation can f
