C++ Problem - Machula/ABSYS
Input je samo prva linija:
machula +123=789
machula+machula=machula
-1989518726+1992205378=2686652
---------------------------------------------------------
Ako nema spaceova, radi kako treba, ali u zadatku pise sa space: http://www.spoj.pl/problems/ABSYS/
(znam da treba i output napisat sa spaceovima)
