is there guaranteed to have at least one space between:

if_<varnum>_==_<varnum>_goto_<label>
<variable>_=_<varnum>_*_<varnum>
("_" denote at least one space)

?

how about brackets "("")"?

or maybe there can exist:

var1 = var2 - -7

?

it's interesting that 1e8 and 1e8+1 both WA on 7...

There are no brackets.
In current tests:
- there are no variables with names "end", "goto",...
- I've just realized that my sol. don't work on "y=x--1", only on "y=x - -1"
- spaces are everywhere, except maybe before and after '+', '=', ':', ...

I think case 11 is WRONG(+)

I don't think so, my sol. never executes my own "END", added after the last line (in that case "exit(1)" would happen).

Spaces are everywhere (-)
