JAVA Code:

Write a program that prints a table of the powers of 2 from 20 up to 2n where n is a given positive integer input from the user. Use four spaces to separate the value of i and 2i in the output. Note: Math.pow() returns a double, but your output should be integers.

Example output of program:

Enter a positive integer: 6 i 2^i 0 1 1 2 2 4 3 8 4 16 5 32 6 64

Starter Code:

import java.util.Scanner; public class PowersOf2 { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); //TODO: complete the program } }
