Note: Problems 2-4 should be defined in a single class (see Solution.java). You do not need to provide main class. The TA will use a main class to test your methods. 2. LARGER THAN N Write a method that accepts two arguments: an array and a number n. Assume that the array contains integers. The method should display all of the numbers in the array that are greater than the number n 3. LO SHU MAGIC SQUARE The Lo Shu Magic Square is a grid with 3 rows and 3 columns. The Lo Shu Magic Square has the following properties: the grid contains 1 through 9 exactly; the sum of each row, each column and each diagonal all add up to the same number; In a program you can simulate a magic square using a two-dimensional array.
