Description

In this exercise, you should exchange the content of two given one dimensional integer arrays with same length.

We have written the code about reading the size and the content of arrays, and we want to pass them to a function for getting the final answer. What you need is helping us to complete the function. 

What input into the function is two pointers representing the two arrays and the length of array, and the function has to exchange the content of the two arrays.

For more specific, you only need to implement the following function:

#include <stdio.h>
#include "function.h"
void array_exchanger(int* array_a, int* array_b, int length) {

     // your code
}

The .c and .h file below might be helpful if you want to know how the function and the whole program works.

Input

The input may have 3 lines of input.

The very first line is a number, representing the length of 2 arrays.

The second and the third lines are several integers, representing the content of 2 arrays.

Output

The content in two arrays after exchanged.
