A shop sells N kinds of fruits, Fruit 1, \ldots, N, at prices of p_1, \ldots, p_N yen per item, respectively. (Yen is the currency of Japan.)
Here, we will choose K kinds of fruits and buy one of each chosen kind. Find the minimum possible total price of those fruits.

-----Constraints-----
 - 1 \leq K \leq N \leq 1000
 - 1 \leq p_i \leq 1000
 - All values in input are integers.

-----Input-----
Input is given from Standard Input in the following format:
N K
p_1 p_2 \ldots p_N

-----Output-----
Print an integer representing the minimum possible total price of fruits.

-----Sample Input-----
5 3
50 100 80 120 80

-----Sample Output-----
210

This shop sells Fruit 1, 2, 3, 4, and 5 for 50 yen, 100 yen, 80 yen, 120 yen, and 80 yen, respectively.
The minimum total price for three kinds of fruits is 50 + 80 + 80 = 210 yen when choosing Fruit 1, 3, and 5.
