Problem Statement

Given are a permutation $P=(P_1,P_2,\ldots,P_N)$ of $(1,2,\ldots,N)$ and a positive integer $K$.

For each $i=K,K+1,\ldots,N$, find the following.

• The $K$-th greatest value among the first $i$ terms of $P$.

Constraints

• $1 \leq K \leq N \leq 5 \times 10^5$
• $(P_1,P_2,\ldots,P_N)$ is a permutation of $(1,2,\ldots,N)$.
• 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

For each $i=K, K+1, \ldots, N$, in this order, print the specified value in Problem Statement, separated by newlines.
