Loop preventing brainfuck

Loop preventing brainfuck is a brainfuck derivative that can be used to solve the halting problem, calculate busy beavers, and solve math problems.

It is also uncomputable.

Commands

Command	Description
>	Move the pointer to the right
<	Move the pointer to the left
+	Increment the memory cell at the pointer
-	Decrement the memory cell at the pointer
.	Output the character signified by the cell at the pointer
,	Input a character and store it in the cell at the pointer
[	Jump past the matching ] if the cell at the pointer is 0
]	Jump back to the matching [ if the cell at the pointer is nonzero
(	Skips after the) if executing the code between braces will not exit
)	Used in conjunction with (
?	Sets the cell at the pointer to a random number 0-255
