3107. 数据交换

输入 n(1<n<11) 个整数，将其中最小数与第一个数交换，将其中最大数与最后一个数交换。

定义 3 个函数：

1） input 输入

2） process 处理交换

3） output 输出

//* Specification of input *

void input(int* p, int n);

/* PreCondition:

p points to an array with n integers

PostCondition:

enter and store n integers into an array pointed by p

*/

//* Specification of process *

void process(int* p, int n);

/* PreCondition:

p points to an array with n integers

PostCondition:

swap smallest number with the first number of an array pointed by p,

and swap largest number with the last number

*/

//* Specification of output *

void output(int* p, int n);

/* PreCondition:

p points to an array with n integers

PostCondition:

print each element of an array pointed by p in one line, with one blank between elements.

*/

只需按要求写出函数定义，并使用给定的测试程序测试你所定义函数的正确性。

不要改动测试程序。测试正确后，将测试程序和函数定义一起提交。
