PLEASE USE Scheme in DrRacket. A. Define a procedure "read-for-square" to read a value for the square procedure defined above. This procedure takes no parameters and will take an input value from keyboard and pass to the Square procedure defined above. > (read-for-square) ; enter 5 from keyboard 25 B. Define a procedure "diff-squares" that will compute the difference between the square values of 2 inputs. You must implement the read-for-square procedure defined above. This procedure should never return a negative value, as it should return the absolute value. > (diff-squares) 5 ; input 10 ; input 75 ; output
