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.

Description
Suppose that we have an encoding scheme defined by the following mapping:
1->'A', 2->'B', 3->'C', ..., 9->'I'
Given a three-digit number N as the input, use the above mapping to encode N.
Input
A three-digit integer N
Output
The encoding result
Note that you do not need to print ‘\n’ at the end of the output.
