1. (15 pts) Write a program that prompts the user to enter
an integer n (assume n >= 2) and displays its largest
factor other than itself.
6
2. (15 pts) Write a method to display a pattern as follows:
1
4 1
9 4 1
16 9 4 1
25 16 9 4 1
…
n*n … 36 25 16 9 4 1

3. (15 pts) Write the following method that returns true if the list is already sorted in
increasing order.

Write a test program that prompts the user to enter a list
and displays whether the list is sorted or not. Here is a
sample run. Note that the first number in the input
indicates the number of the elements in the list.
See the next page for the outline of the program:

else
even = false;
Code 2:
even = (number % 2 == 0) ? true: false;
Code 3:
even = number % 2 == 0;
A. Code 3 has a syntax error, because you attempt to assign number to even.
