Mapfuck 2: Turing Boogaloo

Mapfuck 2: turing boogaloo is a derivative of the original mapfuck programing language made by User:Aspwil (talk) with 2 diffrences

instead of updating the instruction map base on the last char, it updates the map based on the last char and then updates a second time based on the next char in the program

the next and last char are wrapped around to the first and last char of the program

this causes a major problem. while we can take a piece of code and extract the instructions that it generates

if we try to reverse it. and design a piece of code based on a set of instructions we want it is very difficult at best and impossible at worst

here is an example of the program + being run

step 1: assemble the map

this is the default map, put through the previous char`s change table (it's self due to wraping), and then next char`s change table (it's self due to wraping)

so the instruction table becomes

Work Table (showing both changes)

instruction	default	+	+
1	1	1	1
2	2	3	5
3	3	5	2
4	4	7	6
5	5	2	3
6	6	4	7
7	7	6	4
8	8	8	8

Instruction Map

instruction	char #
1	1
2	5
3	2
4	6
5	3
6	7
7	4
8	8

so the instruction for char 3 is instruction 5.

so the program + Outputs the character signified by the cell at the pointer
