Practice Problems in LOLGraphics/Problem II - Greek Numerals

Namer has successfully written a calculator in LOLGraphics and got a free ride to Istanbul. Near the port, he met a cat from the Order of the Tiger who said he will tell the way to the launch location if Namer can write a program in LOLGraphics that converts Arabic Numerals to Greek Numerals. He also gave a page that reads as following:

In order to prove that you are worthy to see the hot air balloon of His Majesty King Battlecat III, you need to first write a code that converts Arabic Numerals to Greek Numerals. Here is a table of Greek Numerals (there are multiple variations, we will be using the modern one for typability):

Arabic	Greek			Arabic	Greek			Arabic	Greek			Arabic	Greek
1	Αʹ			10	Ιʹ			100	Ρʹ			1000	,Α
2	Βʹ			20	Κʹ			200	Σʹ			2000	,Β
3	Γʹ			30	Λʹ			300	Τʹ			3000	,Γ
4	Δʹ			40	Μʹ			400	Υʹ			4000	,Δ
5	Εʹ			50	Νʹ			500	Φʹ			5000	,Ε
6	Ϛʹ			60	Ξʹ			600	Χʹ			6000	,Ϛ
7	Ζʹ			70	Οʹ			700	Ψʹ			7000	,Ζ
8	Ηʹ			80	Πʹ			800	Ωʹ			8000	,Η
9	Θʹ			90	Ϟʹ			900	Ϡʹ			9000	,Θ

So the number 7777 will be written ,ΖΨʹΟʹΖʹ. Assume the number is smaller than 9999 but bigger than 1.
