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) { //TODO: complete this method } }
