Write a Java program to prompt the user to enter an integer n between 1 and 20 both inclusive and (error check is required), then create an array arr of size n. The program then will fill up the integer array with powers of 2, so first element will be 20 , second element will be 2^1 , third element will be 2^2 , forth element will be 2^3 .......... and the last element will be 2n^-1.
