Description
Modify the method that calculates the sum of the integers between 1 and N shown
in slides. Have the new version named Sum.java match the following recursive
definition: The sum of 1 to N is the sum of 1 to (N/2) plus the sum of (N/2 + 1) to
N. Use your program to trace your solution with an N of 7. Then take a screen shot
of the trace and keep the file in your Lab 13 folder. Your program should ask user
to input a number N and calculate the sum of 1 to N. Exceptions should be handled
properly.
What to turn in:
JAR your *.java and the screen shot files into a file called Lab13.jar. When
you’re done, submit the file to Canvas by the deadline. No extensions.
