Test instructions: Ask a bunch of numbers to sort how many times to swap ... This sorting method did not see what it was when reading the question ... Later Baidu said it was bubbling, that is, it is a problem of the number of reverse order.Solution:
First, merge Sort methodMerge sort is an efficient or relatively high algorithm. The divide-and-conquer approach is often used as a solution to this problem, and today's popular cloud computing is in fact a sort of application of the
Array merge issues
$act _arr = Array (0=> ' AAA ',2=> ' BBB ');
I'm going to turn into the following string
' AAA ', ' BBB '
Use implode (', ', $act _arr);
The result is aaa,bbb.

1. To give a word a, if another word B can be obtained by exchanging the letter order in the word, B is the brother word of A, for example, the word army and Mary are brother words.Now we need to provide a solution to find out which brothers of
The specific requirements are as follows:
1. The date table is filled horizontally.
2. The date list of each month is displayed in a horizontal row, instead of displaying a square like many date controls on the Internet.

Old saying:
Insert sorting worst case O (n2) with compact loops. For small-scale input, it is a fast in-situ Sorting Algorithm (a part in the array. Merge Sorting has a gradual running time (nlgn time), and merge is not performing in-situ operations
However, because mobile phones have many parameters and their parameters vary greatly, the parameter table structure is generally a vertical table (one parameter is a row ), instead of a horizontal table (a parameter is a column), several parameters
