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.

Description
Caesar wants to eat salad, but nobody sells salad within his country. Thus, he decides to write a letter to the businessmen outside his country. But to secure his message, he has to encrypt the content of his letter.
The encrypt rule is as follow: For each English character inside his letter, shift it with a fixed number n in positive/negative direction.
For example,
- n = 2, then "IJK" will become "KLM"
- n = 3, then "IJK" will become "LMN"
- n = -2, then "AJK" will become "YHI"
- We do the shifting in a cyclic manner, that is, perform left shift 1 on "A" will become "Z"; right shift 2 on "Y" will become "A"
Actually, this encryption is the well-known Caesar chiper.
Input
Input consists of three UPPERCASE English characters and an integer n, seperated by a whitespace character.
The three uppercase English characters is the Caesar's message, n is the shift amount mentioned above (positive for right shift, negative for left shift).
It is guaranteed that -2147483648 <= n <= 2147483647.
Output
Print Caesar's message after encryption (three UPPERCASE English character).

Description
Converting temperature between Celsius and Fahrenheit is a basic skill. You are asked to write a program which can do such task automatically. The following is the conversion rule:
Input
Given a integer t and two chars x, y ( 'C' or 'F'). Please convert the temperature t from unit x to y.
(0 <= t <= 1000)
Output
Output the answer, which is a floating point rounded to 2nd decimal places.
Please print '\n' in the last line.
