A company sells its products at N outlets. All the outlets are connected to each other by a series of roads. There is only one way to reach from one outlet to another. Each outlet of the company has a unique outlet ID. Whenever the inventory of a certain product reaches a minimum limit then these K outlets make a request for extra inventory. The company sends the requested products from its warehouse to the outlets. In order to save on fuel, the warehouse supervisor directs the driver Mike to deliver the products to the outlets along the shortest and most direct path possible, without traveling any single road twice.Write an algorithm to help Mike deliver his inventory to the maximum number of outlets without traveling any road twice.Input:The first line of the input consists of an integer - num, representing the total number of outlets of the company including the warehouse (N).The second line consists of an integer- koutletsCount, representing the outlets that requested the extra inventory (K).The third line consists of K space-separated integers representing the outlet IDs of the outlets that requested the extra inventory.The fourth line consists of two space-separated integers-numR and conOutlet, representing the total number of roads between two outlets including the warehouse (numR (M) is always equal to N-1) and number of outlets connected by a road (conOutlet (X) is always equal to 2). The next M lines consists of X space-separated integers representing the road between two outlets.OutputPrint an integer representing the maximum number of outlets that Mike can cover in a single trip without travelling any road twiceConstraints0 <= koutletsCount <= nums <= 10^51 <= nums <= 10^51 <= A,B <= num; where A, B represent the outlets connected by a road numR=num-1Example:Input:432 3 43 21 21 31 4Output:2
