Question 1126: print the subscript of the Extreme PointDescription:
In an integer array, for an integer whose subscript is I, if it is greater than all its adjacent integers,Or smaller than all its adjacent integers, it is called this Integer as an extreme point, the subscript of the extreme point is I.
Input:
The input for each case is as follows:
There are 2 × n + 1 rows of input: the first row is the number of arrays to be processed n;For the remaining 2 × n rows, the first row is the number
for conversion between Java objects and Json strings;
The json Development Kit has a total of three jar: ezmorph-1.0.6.jar, json-lib-2.2.3-jdk13.jar and morph-1.1.1.jar.
These three jar packages have been uploaded to CSDN.
Sample Code:

The call_user_func function is similar to a special method for calling a function. the usage is as follows:
Function a ($ B, $ c)
{
Echo $ B;
Echo $ c;
}
Call_user_func ('a, "111", "222 ");
Call_user_func ('a, "333", "444 ");
// Display 111

When I look at the UCenter, there is a function call_user_func, which is puzzling, because I thought it was a self-defined function and the results were not found everywhere, later, Baidu learned that call_user_func is a built-in function called call_user_func, which is similar to a special method to call a function. the usage is as follows:

First, create a new arrayThe array has no size limit, so you can create an array simply by creating a reference, for example: $state [0]= ' 111 '; $state [1]= ' 222 '; If the index value is a numeric index and is incremented, the index value can also be omitted at creation time.$state [] = ' 111 '; $state [] = ' 222 ';Arrays can be created using array (), such as: $state =array (' 111 ', '
