Cocos2d-x 3.2 packaging error Summary
1. During packaging, the environment must be properly configured; otherwise, various errors may occur. If the environment is configured, but the file path is changed later,
The system will prompt that the path cannot be found. Therefore, after the environment is configured, files such as adt, ndk, ant, and jdk cannot be moved at will.2. In the cocos2d-x3.2 version, replace the previous Code in Application. mk under the jni directory with: APP_STL: = gnustl_s
directly thought of A solution: read Table B in Python and obtain data in the form of {id: age, then, update Table A based on the values of each ID and age.The two tables define and data respectively as follows:
Table A definition:

Id
Int (11)
Name
Varchar (20)
Age
Int (11)
Data:
1, name1, 02, name2, 03, name3, 04, name4, 05, name5, 0
Table B definition
Field
Type

In other words, a quick sort is a good sorting scheme for larger arrays, but if the arrays are very small, then the fast sort algorithm is better than the direct insert sort (the direct insert sort is the best performance in a simple sort). The reason for this is that a recursive operation is used for fast sequencing, which can be ignored when a large amount of data is sorted, which is negligible relative to its overall algorithm advantage, but if the array has only a few records to order, it

Solution: The scanning line of a line segment, assuming a bit (x, y), then (x, y )~ A rectangle (x + W, y + H) can be enclosed at (x, y) points in the lower right corner of the frame. Therefore, N points are N rectangles, find the maximum number of times covered, scan line bare question. # Incl

say this feature PHP seems to have: $my _array = Array ("Dog", "Cat", "Horse"); list ($a, $b, $c) = $my _array; but it doesn't matter at all.4, "PHP can continue to live today mainly because the first can adjust the C module, so rely on C programmers step by step, Swoole is the same;" PHP is the CPU-intensive function C module is for performance Ah, what is the black?

People describe a point or a position in a space, usually using the concept of coordinates. But how do we calculate this coordinate? Who does it refer to?
