@bhaskar ur algo fails on this case (5+3)-(2+(3/6)) -+53+2/36 63/2+35-+ showing that 6/3 but actually it is 3/6 so i think it could be done by folowing algo make a binary tree of given expression in O(n) then do postorder traversal take O(n) so problem can be solved in O(n). and take O(2*n+1) space
