Problem Statement

You are given a permutation PP of 1,2,,N1, 2, \cdots, N.

You can divide PP into exactly KK non-empty contiguous subsequences as you like.

Maroon will rearrange those subsequences you make and concatenate them to make a new permutation QQ. Here, he will lexicographically maximize QQ.

You want to divide PP in a way that lexicographically minimizes QQ. Find QQ in that case.

Constraints

  • 1N2×1051 \leq N \leq 2 \times 10^5
  • 1KN1 \leq K \leq N
  • 1PiN1 \leq P_i \leq N
  • PiPj(ij)P_i \neq P_j (i \neq j)
  • All values in input are integers.

Input

Input is given from Standard Input in the following format:

NN KK

P1P_1 P2P_2 \cdots PNP_N

Output

Print QQ when you optimally divide PP.

3 2
1 2 3
2 3 1

You have two ways to divide PP: (1,2),(3)(1, 2),(3) and (1),(2,3)(1), (2, 3).

In the former case, Maroon will rearrange them in the order (3),(1,2)(3), (1, 2) to get Q=(3,1,2)Q = (3, 1, 2).

In the latter case, Maroon will rearrange them in the order (2,3),(1)(2, 3), (1) to get Q=(2,3,1)Q = (2, 3, 1).

Thus, you should choose the latter.
