啊！

"啊！" is a Esolang same as "Ook!".

The founders of the "Ook!" thought that the programming language could even be learned by orangutans, so they didn't open up the comment function.

If you wanna learn "啊！", you must learn Brainf*ck.

The syntax

"啊！" has only THREE SYMBOLS (but 8 commands): "啊。", "啊？" and "啊！".

Caption text

啊！	Brainf*ck	Mean
啊。啊？	>	Move the pointer one cell to the right.
啊？啊。	<	Move the pointer one cell to the left.
啊。啊。	+	Increase the pointed data.
啊！啊！	-	Decrease the pointed data.
啊。啊！	,	Read a character from STDIN and dump its Unicode into the cell.
啊！啊。	.	Print the character with Unicode value equal to the value in the cell pointed at by the Memory Pointer.
啊！啊？	[	Move to the command following the matching 啊？啊！ if the value in the cell pointed at by the Memory Pointer is zero. Note that 啊！啊？ and 啊？啊！ commands nest like pairs of parentheses, and matching pairs are defined in the same way as for parentheses.
啊？啊！	]	Move to the command following the matching 啊！啊？ if the value in the cell pointed at by the Memory Pointer is non-zero.
啊？啊？	NOP	It didn't do anything, just wait for 1 seconds...

So, a 啊！ program needs even number(such as 2, 4, 6 or 8) "啊！"'s.
