Primes and Perfect Squares
                    
                        A Prime Number is a natural number greater than 1 and can only
                        be divided by 1 and itself.
                        
                        Examples: 1,3,5,7,11 ... are prime numbers. They can not be divided
                        by any number to give a whole number.
                        
                        A Perfect Square is a number that is equal to the square of another
                        number.
                        Examples: 4,9,16,25,... are the perfect squares of 2,3,4,5 respectively.
                    
                    
                        Prime Numbers and Perfect Square are mutually
                        exclusive. This means a prime number cannot be a perfect square and nor can a perfect
                        square be a prime number.
                        
                        Use the following program to find all prime numbers and perfect squares between
                        two numbers. They appear on the same visual grid because they are mutually exclusive.
