Create a word document or text file named part3 that contains answers to the following:

1. consider the declaration in sumallarr. java: int[] arr1 = new int[max + 1];
a. how many array elements does this statement create?
b. why do we have max + 1?
c. can we just use max and have the program still work correctly?

2. before the while-loop in sumallarr. java we have i = 1.
a. why is it there?
b. can we use another variable instead?

3. the do-while loop in sumallarr. java is implemented using (++i < = max).
a. provide an alternative expression that implements the same logic.
b. what will (i++ < = max) result in?
