 # If the expression a b + c d + ⋅ in postfix notation is converted to infix notation, what is the result? b. Let ∑ = { 1 , 2 , * , / } and let L be the set of all strings over ∑ obtained by writing first a number (1 or 2), then a second number (1 or 2), which can be the same as the first one, and finally an operation (denoted * or /, where * indicates multiplication and /indicates division). Then L is a set of postfix, or reverse Polish, expressions. List all the elements of L between braces, and evaluate the resulting expressions. ### Discrete Mathematics With Applicat...
