	* function isCompositeNumber
	* Check if a given number is a composite number or not?
	* isCompositeNumber(6) // returns true
	* isCompositeNumber(577) // returns false
	* isCompositeNumber(2024) // returns true
	* A composite number is a positive integer that is not prime. In other words, it has a positive divisor other than one or itself.
	* First few composite numbers are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, .........
	* Every integer greater than one is either a prime number or a composite number.
	* The number one is a unit – it is neither prime nor composite.
