Write a program that converts temperature to Celsius if it's given in Fahrenheit (input will have an 'F' after the number), or vice versa, if it's given in Celsius (input will have a 'C' after the number).

At least two decimal places must be exact. Other decimals are ignored.

If C is the temperature in Celsius, the conversion formula to Fahrenheit is: F = 32 + 9*C/5.0

If F is the temperature in Fahrenheit, the conversion formula to Celsius is: C = 5*(F-32)/9.0

Input

One line with an integer number (between -200 and 100), a space, and a letter ('C' or 'F')

Output

The temperature converted, in the same format as the input (a number, a space, and a letter 'C' or 'F' indicating if it was converted to Celsius or Fahrenheit, respectively.

Example

Input:
22 C

Output:
71.60 F
