After a few months of playing on his new phone, Mirko has finally decided to find a new hobby. He discovered a card game called bridge!

It is known that bridge is played by four players using a -card deck, suits total (`clubs`

, `hearts`

, `diamonds`

and `spades`

) and 13 values (`A`

, `K`

, `Q`

, `J`

, `10`

, `9`

, `8`

, `7`

, `6`

, `5`

, `4`

, `3`

and `2`

). At the beginning of the game, each player is dealt cards.

Before starting the game, each player counts their so-called honor points in the following way:

- each ace (
`A`

) is worth points - each king (
`K`

) is worth points - each queen (
`Q`

) is worth points - each jack (
`J`

) is worth point - the remaining cards (that will be denoted with
`X`

in this task) are worth points.

Given the fact that Mirko has started playing bridge only recently, he has decided to practice counting points. He dealt himself cards times and each time counted his honor points. In the end, he added them up.

He wants to know if he's done a good job. Help Mirko and check!
