Given an array A of size n i.e., A = {A_1, A_2, ... A_n} you are given K. you can choose any K integers (not necessarily from the given array) i.e, X_1, X_2, X_3 .... X_K
Now, we define a function F for each A_i, such that F_i = min(abs(A_i — X_j)) where 1<= j <=K.
find the minimum value of F_1 + F_2 + .... F_n.
constraints:
1 <= n <= 10^5 1<= K <= n
