java getDup accepts an array and returns an int. If there is any element is duplicated, the method counts how many of those present in the array. Example : getDup(["1","2","aa"',"1"]) returns:2 ("1" is duplicated and there are two "1"s so return is 2) class Main { public static int getDup(String[] r) { } public static void main(String[] args) { Scanner in = new Scanner(System.in); String [] strs = new String[in.nextInt()]; for(int i=0; i < strs.length; i++) { strs[i] = in.next(); } System.out.println(getDup(strs)); } } hint: you will need a nested array the will run on the array we get from the method argument. inside the nested loop you will need to check if the main array element is equal to the current

in java wirte a method that given an integer array, computes and returns an integer x. the starting value of x is equal to the array length. for every odd element in the array, substract it from x, and for every even element in the array add it to x . Example: Array: [13,2,3,4,5] Result: x=5-13+2-3+4-5 x= -10
