Problem Statement
You are given $a permutation P=(P_1,P_2,\dots,P_N)$ of integers from 1 to N and an integer K.
Consider the following operation on the permutation P.
- Choose an integer i such that $1 \leq i \leq N-K+1$, and sort $P_i,P_{i+1},\dots,P_{i+K-1}$ in ascending order. That is, let $(x_1,x_2,\dots,x_K)$ be the result of arranging $P_i,P_{i+1},\dots,P_{i+K-1}$ in order from smallest to largest, and replace P_{i+j-1} with x_j for each $1 \leq j \leq K$.
Find the lexicographically largest permutation that can be obtained by performing the above operation on P exactly once.
What is lexicographical order on sequences?
$A sequence S = (S_1,S_2,\ldots,S_{|S|})$ is lexicographically smaller than $T = (T_1,T_2,\ldots,T_{|T|})$ when 1. or 2. below holds.
Here, |S| and |T| denotes the lengths of S and T, respectively.
- $|S| \lt |T|$ and $(S_1,S_2,\ldots,S_{|S|}) = (T_1,T_2,\ldots,T_{|S|})$.
-
There is an integer $1 \leq i \leq \min\lbrace |S|, |T| \rbrace$ that satisfy both of the following:
-
$(S_1,S_2,\ldots,S_{i-1}) = (T_1,T_2,\ldots,T_{i-1})$.
- S_i is smaller than T_i (as a number).
Input
The input is given from Standard Input in the following format:
N K
$P_1 P_2 \dots P_N$
Output
Print the lexicographically largest permutation that can be obtained by performing the above operation on P exactly once, with spaces in between.
Constraints
- $1 \leq K \leq N \leq 2 \times 10^5$
- $1 \leq P_i \leq N$
- $(P_1,P_2,\dots,P_N)$ is a permutation of integers from 1 to N.
- All input values are integers.

If you perform the operation with i=1, we have (P_1,P_2,P_3)=(2,1,4), and sorting it in ascending order yields (1,2,4). Thus, the operation replaces P_1,P_2,P_3 with 1,2,4, respectively, resulting in P=(1,2,4,3). Similarly, if you perform the operation with i=2, P becomes (2,1,3,4).
The lexicographically greater between them is (2,1,3,4), so the answer is (2,1,3,4).
