Description
The input is a four-digit integer N that consists of digits 1-9 except 0. For example, 1234 is such a number. The task is to rotate the digits of N left an right to get two new four-digit number M and P, and compute the product of the M and P. For example, if N is 1234, then M is 2341and P is 4123, and the answer should be 9651943.
Input
A four-digit integer consisting of 1-9 except 0
Output
The product of its left rotation and its right rotation
Note that you do not need to print ‘\n’ at the end of the output.

Description
The input is a three-digit integer N that consists of digits 1-9 except 0. For example, 489 is such a number. The task is to reverse the order of the digits of N to get a new three-digit number M, and compute the average of the N and M. For example, if N is 489, then M is 984, and the answer should be 736.5.
Input
A three-digit integer consisting of 1-9 except 0
Output
The average of the input number and its reversal
The answer should be expressed as a floating point number with precision to the first decimal place. For example, 333.0 or 736.5
Note that you do not need to print ‘\n’ at the end of the output.
