With the IPL going on, the Sharjah Cricket Stadium management is trying to figure out the optimal strategy for ticket sales.* There are M rows in the stadium with different seating capacities. They may or may not be equal. The price of the ticket depends on the row. If the row has K (always greater than 0) vacant seats, then the price of the ticket will be K dollars. Now, every fan standing in the line will get a ticket one by one. Given the seating capacities of different rows, find the maximum possible dollars that the stadium will gain with the help of the ticket sales. Input: The first line consists of M and N. M denotes the number of seating rows in the stadium and N denotes the number of football fans waiting in the line to get a ticket for the match. Next line consists of M space separated integers X[1,X[21,X[31. X[M] where X[i] denotes the number of empty seats initially in the ith row. Output: Print in a single line the maximum dollars the stadium stands to gain. Constraints: 1
