Given a musical key, output its number and letter on the Camelot Wheel (shown below).

Camelot Wheel

Input

A musical key as a string, as shown on the wheel. The words "Sharp" and "Flat" may be replaced with symbols (such as "#" and "b") if you wish.

Output

The number and letter, either as a string, tuple, or array.

Examples:

Input->Output
"E Major" -> "12B"
"F-Sharp Minor" -> "11A"
"Bb Minor" -> "3A"

This is code-golf.

This is suprisingly hard to compress well.

I know it's not directly related to the challenge, but reading the phrase "D-Flat Minor" gave me an aneurysm. (D-Flat Minor has 6 flats and a double flat, C# minor is just 4 sharps, way easier to work with)
