题目描述

Chef likes arrays a lot. Today, he found an array A consisting of N positive integers.
Let L denote the sorted (in non-increasing order) list of size N*(N+1)/2 containing the sums of all possible contiguous subarrays of A. Chef is interested in finding the first K elements from the list L. Can you help him in accomplishing this task?

Input
There is only a single test case per input file.
The first line of input contains two space separated integer numbers N and K denoting the size of the array and the number of the maximal sums you need to find.
The following line contains N space separated integer numbers denoting the array A.

Output
Output K space separated integers where the i^th integer denotes the i^th element of L.

Constraints

1 ≤ N ≤ 10^5

1 ≤ K ≤ min(N*(N+1)/2, 10^5)

1 ≤ Ai ≤ 10^9
