An events ticket booking System prompts the user to make a choice as well as the number of tickets required. It then displays the total cost of the order. The menu options and cost per ticket is as follows: 1 Exclusive VIP area A : R3 000.00 2 VIP area B : R2 000.00 3 Elevated area :R1200.00 4 General area R600. 0 QUIT

Create an AVL tree with the following keys,clearly show visually each step.Each step wil contain a mark.

12,33,44,43,99,0,88,13,43,2,222

Convert the expression into postfix notation and then verify if it is correct or not,direct answers for both 5conversion are not allowed for verification take dummy values for eachvariable.

a+b*(c/d-e)%(f+g*h)-i

Note:

1)No code is required.

Convert the follwoing expressio to postfix notation. Show the state of stack and expression after each step.

( ( 2 * ( 6 + 3 ) ) / ( 4 - 6 + 4 ) ) / 5

Note:

1)no code is required.

Convert the given postfix expression into equivalent infix expression.Show all steps ,no marks will be given for direct answer.

a b + c -d e * /

the out put should be 12x^4 + 9x^3 - 5x^2 - x - 1 but our code does not give this out put
