Recently, Pero has been into robotics, so he decided to make a robot that checks whether a deck of poker cards is complete.

He's already done a fair share of work - he wrote a program that recognizes the suits of the cards. For simplicity's sake, we can assume that all cards have a suit and a number. The suit of the card is one of the characters P, K, H, T, and the number of the card is an integer between ~1~ and ~13~. The robot labels each card in the format TXY where T is the suit and XY is the number. If the card's number consists of one digit, then ~X = 0~. For example, the card of suit P and number 9 is labelled P09.

A complete deck has ~52~ cards in total - for each of the four suits there is exactly one card with a number between ~1~ and ~13~.

The robot has read the labels of all the cards in the deck and combined them into the string ~S~. Help Pero finish the robot by writing a program that reads the string made out of card labels and outputs how many cards are missing for each suit. If there are two exact same cards in the deck, output GRESKA (Croatian for ERROR).

Input Specification

The first and only line of input contains the string ~S~ ~(1 \le |S| \le 1000)~, containing all the card labels.

Output Specification

If there are two exact same cards in the deck, output GRESKA.

Otherwise, the first and only line of output must consist of 4 space-separated numbers: how many cards of the suit P, K, H, and T are missing, respectively.

Sample Input 1

P01K02H03H04

Sample Output 1

12 12 11 13

Explanation for Sample Output 1

The robot has read 1 card of the suit P, 1 card of the suit K, 2 cards of the suit H.

Sample Input 2

H02H10P11H02

Sample Output 2

GRESKA

Explanation for Sample Output 2

There were two cards of the suit H with number ~2~, so the robot reports an error.

Sample Input 3

P10K10H10T01

Sample Output 3

12 12 12 12
