mealy | Model Error Analysis for scikit-learn models | Machine Learning library

I'm trying to implement a very simple Mealy state machine in Verilog. I have already done it with case and if statements, but I want to be able to do the same using a 2D array as transition table, for clarity.

Here is the code:

I'm trying to make my own syntax highlighting in Ace. So far I did this:

1. cloned ace repo git clone https://github.com/ajaxorg/ace.git
2. used Iro to design some syntax. Later I pasted the code generated by Iro into mode creator and it seems to be working perfectly fine.
3. I copied the code generated by Iro and put it in ace/lib/ace/mode/mealy.js
4. run npm install in ace directory
5. run node ./Makefile.dryice.js in ace directory. I ac successfully see ace/build/src/mode-mealy.js.
6. I created this embedding code

I'm building a visitor counter in my room using Arduino, IR transmitter, and two SHARP IR sensors. The sensors count the number of people in my room - one person turns up the light, more do nothing, and zero turns the light off. The IR transmitter works great (it turns the light on/off) so as the detection, but I have a problem and a question.

My question is, is there an option to make a function and call it twice instead of repeating myself inside the loop? if so, how? they are mostly symmetric, but still have some differences like the flags and num_people manipulating.

My main problem right now is counting num_people and I found out that this line is the problem: num_people = (num_people > 0) ? num_people-1 : 0; When I put this line in a comment I can count more than one person, but when I'm not it runs over the code and counts 1,0,1,0,1,0 (only when getting inside the room). Need to say that when I go out it decreases num_people as it should and when on zero keeps that number.

The code is here:
