An interesting question came across my mind: If it is possible to convert a percentage to a Grade(A,B,C,D, or an F). Firstly, there is an easy method to convert a percentage to a Grade; by using an If and Else loop. However, are there also other methods with which this can be achieved? Arrays, shiftin bits, etc... It would be very interesting to see if there are any non-trivial methods to this.
