Temperature stored in Celsius

Problem

A weather app gets readings in either Celsius or Fahrenheit but always stores Celsius, and shows both. F = C × 9 / 5 + 32.

Write a class Temperature with one field celsius, a method double fahrenheit() and a method void setFahrenheit(double f) that converts and stores the value in celsius. Use one object per reading.

Input, output and limits

Input: The first line has an integer t. Each of the next t lines is C value or F value.
Output: t lines: c C = f F, both with one digit after the decimal point.
Constraints: 1 ≤ t ≤ 100
-1000 ≤ value ≤ 1000, with at most one digit after the point

Examples

Example

Input

3
C 37
F 212
C -40

Output

37.0 C = 98.6 F
100.0 C = 212.0 F
-40.0 C = -40.0 F

37 °C is 98.6 °F, 212 °F is boiling water, and -40 is the same in both scales.

Hints

Try the problem first. Open one hint at a time.

Hint 1

For C, set the field directly; for F, call setFahrenheit.

Hint 2

The reverse formula is C = (F - 32) × 5 / 9.

Hint 3

Only celsius is stored, so fahrenheit() always works it out from the field.
