***C PROGRAMMING***

Need help with a C program array_rearrange.c that rearranges an integer array. The array will be split into two sets of integers one by one. A new array will be created by append the first set to the second set. For example, an integer array {1, 2, 3, 4, 5, 6} will be split into two sets of integers: 1, 3, 5 and 2, 4, 6. Merging result: {2, 4, 6, 1, 3, 5}. Note that the two sets do not necessarily have the same length (when the array has even number of elements). When the input word has odd number of elements the first set will be one element more than the second set. For example, the result of rearranging an integer array {1, 2, 3, 4, 5} will be {2, 4, 1, 3, 5}. Your program should include the following function: void rearrange(int *a1, int n, int *a2); 

The function should use pointer arithmetic - not subscripting - to visit array elements. The rearrange function merges the two sets of integers by appending the first set to the second set and store the result in the second array a2. The function takes an int array parameters a1 and 2 as the first parameter and third parameters and the number of elements of the arrays as the second parameter.  

Example I/O:

Enter the length of the array: 5 

Enter the elements of the array: 9 8 5 6 4 

Output: 8 6 9 5 4
