1- Evaluate the following postfix expressions and write out a
corresponding infix expression:
2 3 2 4 * + *
12 - 3 2 ^ 3 * 6 / +
123 4 ^ **
25 ^ 1 -
2 Convert the following equations from infix to postfix:
2 ^3 ^ 3 + 5* 1
2 33 ^^ 51* +
11 + 2 -1* 3/ 3 + 2 ^ 2/3
11 + 13* 3/- 22 ^ 3/+
3- Evaluation using stack
1 - 2 ^ 3 ^ 3 - ( 4 + 5 * 6*7 ) * 8
Show algorithm in action on above equation
4- Expressions, programs, etc can be represented by tree
structures
E.g. Arithmetic Expression Tree
A-(C/5 * 2+7) + (D*5 % 4)
5-Draw the binary search tree that would result from the
insertion of the following integer keys:
