Your task is to write a program that will take as input an integer, and swap its left half with itsright half.

[mehrankhan]

Note that if the length of the integer is odd, then the left half will contain the digit in
the exact middle position (for example: the left half of 65237 is 652, and the right half is 37).

Sample Input: 984897 > Sample Output: 897984
Sample Input: 65237 > Sample Output: 37652
