Complete the method, isPerfectSquare(). The method takes in a positive integer, n. It returns a boolean that is true if n is a perfect square, false otherwise. A perfect square is an integer whose square root is also an integer. You may assume that n is a positive integer. Hint: find the square root of n, cast it to an int value, then square it and compare this square to n.
Starter code:-
public class Square {
public static boolean isPerfectSquare(int n) {
