Edward is on his way to visit his Grandma,Who lives at the end of the state.
It’s her birthday, and he want to give her the cakes that he has made.
Between his place and her grandma house,
he need to cross 7 toll bridges.
Before you can cross the toll bridge,
you need to give them half of the cakes you are carrying,
but as they are kind trolls,
they each give you back a single cake.
How many cakes does Edward have to carry with him
so he can reach his grandma home with exactly 2 cakes?
He should carry only two cakes..
