Can i replace position of + and =?
For example can i answer for
1+12=13
100
----
11+2=13

Are there leading zeroes in input, and can i output answer with leading zeroes?

1) Yes
2) Statement is now updated

I have similar question about relative order of + and =. E.g. can the answer become
3=1+2
?

One more thing should be added to problem statement - new sequence must be left/top-aligned with original one. E.g. it should be impossible to convert 1+33=441 into 11+33=44 by moving rightmost 1 to the left. I tried that when I struggled WA40, but this extension gave WA9.

(WA40 was wrong paint of digit 2 :)
