Write a Java program takes a positive integer n as the first command line argument (that is, args[0]) and uses a for loop to calculate the sum of 1.0 2 i for all odd integers i in the range 1 to n. Note: the fraction 1.0 2i should be evaluated as a double to avoid integer division. Call the program HW3Sum.java. The first line of text should be your name. The second line should be the calculated sum. If the value n is non positive, print out a error message.
