Just wanna have it checked if i'm doing this rightly...
i was given an expression to translate it into a polish notation and traversals.
the expression is
{( a + b ) - c } * { d * (e / f + g)}
here's my answer:
POSTFIX : a b + c - d e f g + / * *
PREFIX : * - + a b c * d / e + f g
PRE-ORDER : * - + a c b * d / e + f g
POST-ORDER: a b + c - f g + e / d * *
IN-ORDER : a + b - c * d * e / f + g
No, you aren't.
No, you aren't.
awww... :(
can you please help me understand this?
Why is your prefix notation and preorder traversal any different?
Why is your prefix notation and preorder traversal any different?
:(
that's how i understood it... :(
should they always be the same?
i'll try it again
pre-order:
* - + a b c * d / e + f g
post-order:
a b + c - f g + e / d * *
in-order:
a + b - c f + g e / d * *
