Complete the function that takes a non-negative integer n as input, 
	and returns a list of all the powers of 2 with the exponent ranging 
	from 0 to n ( inclusive ).
	Examples
		
	n = 0  ==> [1]        # [2^0]
	n = 1  ==> [1, 2]     # [2^0, 2^1]
	n = 2  ==> [1, 2, 4]  # [2^0, 2^1, 2^2]
				

Solution by -

	function powersOfTwo(n){
		let arr=[1]
		for(let i=1; i<=n; i++){
		arr.push(Math.pow(2,i))
		}
		return arr
	}
