~~: I learned something new today.
the while conditions, and the way u use res is very good but...
wew... took me a while to figure out what ur doing with c... true = 1, false = 0... useing that is brilliant.

Javascript: I have no idea where I need to start from. What does test cases gives in? what does my code need to give out... I am not that familiar with objects yet...

maybe it is intended but in R the function name that is writen in draft, is not what test calls.

hmmm so u can give true to 2 simply by changing when u increase i....
++i good one, didnt thought of that.

19.99999999999993 now.... thats a dilemma...

Tried to do this for hours didn't worked... Then I solved it with 35 line of for and if codes,
I should have ss what I wrote back then... know I dont even know what was wrong with it...

nwm I realized, answer to 1st question is there. and it can only be true if everything else in x,y is initially dead.

I didnt get 1 thing from this part;
"The universe is infinite in both the x and y dimensions and all cells are initially dead - except for those specified in the arguments."
so does it mean that 3x3 cells we are given repeats(some alive and some dead) in x and y direction, or outside of 3x3 there are only dead cells in x and y direction?

Question does not give u an array, but a string.
Maybe it will help you solve it.
