Write an algorithm to calculate a postfix expression. Execute your algorithm using the given postfix expression as your input : a b + c d +*f ↑ .
To evaluate a postfix expression by using the given values:
clear the stack
symb = next input character while(not end of input)
{
if (symb is an operand)
push onto the stack;
else
pop two operands from the stack;
result=op1 symb op2;
push result onto the stack;
}
symb = next input character;
return (pop (stack));
The input postfix expression is given as:- ab+cd+*f^
Symb Stack Evaluation a a
b a b
+ pop a and b (a + b) Push (a + b)
c (a + b) c
d (a + b) c d
+ pop c and d (c + d) Push (c + d)
* pop (a + b) and (c + d) (a + b) * (c + d)
f (a + b) * (c + d) f
^ pop (a + b) * (c + d) and f (a + b) * (c + d) ^ f
The result of evaluation is ((a + b) * (c + d)) ^ f

For preorder traversal, in the worst case, the stack will rise to size n/2, where n refer to number of nodes in the tree. Another method of traversing binary tree non-recursively t
Insertion: Records has to be inserted at the place dictated by the sequence of keys. As is obvious, direct insertions into the main data file would lead to frequent rebuilding of
An interesting application or implementation of trees is the playing of games such as tie-tac-toe, chess, nim, kalam, chess, go etc. We can depict the sequence of possible moves

Q. Devise a representation for a given list where insertions and deletions can be made at both the ends. Such a structure is called Deque (which means Double ended queue). Write fu
