A. Convert the expression to equivalent Postfix notations. Show all the steps involved in conversion [(A+B)/(C+D)^(E+F)]+(G+H]/I B. Write a function called "ScanExpression()". This function will scan the mathematical expression and checks whether the expression is true or false. You have to check the expression using stack. Note: You only have to check scope delimiters. If the scope delimiters are in order i.e. closing scope should be preceded by opening scope
