tricky problem... do's it come from a challenge?

result: a == 10 and b == 10

details:

a=9 : 9 in a => a == 9
b=9 : 9 in b => b == 9
a=b++ : b(9) in a, then b=b(9)+1=10 => a == 9, b == 10
b=a++: a(9) in b, then a=a(9)+1=10 => a == 10, b == 9
b=++b : b=b(9)+1=10 (++b), then b in b => a==10, b == 10

Answer 2

this is the only one output possible, in any languages wich have incrementation/decrementation operators, but that's a tricky case, as you will almost only encounter it in test questions ;)
