问题描述

有一副包含 $N$ 张面朝下的扑克牌，每张牌上都写有一个从 $1$ 到 $N$ 的整数。第 $i$ 张从顶部开始的牌上的整数为 $P_i$。

使用这副牌，你需要执行 $N$ 次操作，每次操作包括以下步骤：

• 从牌堆顶部抽一张牌。设此牌上所写的整数为 $X$。
• 将抽出的牌（面朝上）放在桌面上所有面朝上的最顶部牌中，整数值大于等于 $X$ 的最小整数值的牌之上。如果桌面上没有这样的牌，则将抽出的牌面朝上放在桌面上，不叠加在任何牌上。
• 接着，如果桌面上有由 $K$ 张面朝上的牌组成的一堆牌，吃掉所有这些牌。被吃掉的牌都会从桌面上消失。

对于每张牌，请找出它在哪一次操作中被吃掉。如果该牌直到最后都没有被吃掉，则报告这一事实。

Problem Statement

There is a deck consisting of $N$ face-down cards with an integer from $1$ through $N$ written on them. The integer on the $i$-th card from the top is $P_i$.

Using this deck, you will perform $N$ moves, each consisting of the following steps:

• Draw the topmost card from the deck. Let $X$ be the integer written on it.
• Stack the drawn card, face up, onto the card with the smallest integer among the face-up topmost cards on the table with an integer greater than or equal to $X$ written on them. If there is no such card on the table, put the drawn card on the table, face up, without stacking it onto any card.
• Then, if there is a pile consisting of $K$ face-up cards on the table, eat all those cards. The eaten cards all disappear from the table.

For each card, find which of the $N$ moves eats it. If the card is not eaten until the end, report that fact.

Constraints

• All values in input are integers.
• $1 \le K \le N \le 2 \times 10^5$
• $P$ is a permutation of $(1,2,\dots,N)$ (i.e. a sequence obtained by rearranging $(1,2,\dots,N)$).

Input

Input is given from Standard Input in the following format:

$N$ $K$

$P_1$ $P_2$ $\dots$ $P_N$

Output

Print $N$ lines.
The $i$-th line ($1 \le i \le N$) should describe the card with the integer $i$ written on it. Specifically,

• if the card with $i$ written on it is eaten in the $x$-th move, print $x$;
• if that card is not eaten in any move, print $-1$.

Sample Input 1

5 2
3 5 2 1 4

Sample Output 1

4
3
3
-1
4

In this input, $P=(3,5,2,1,4)$ and $K=2$.

• In the $1$-st move, the card with $3$ written on it is put on the table, face up, without stacked onto any card.
• In the $2$-nd move, the card with $5$ written on it is put on the table, face up, without stacked onto any card.
• In the $3$-rd move, the card with $2$ written on it is stacked, face up, onto the card with $3$ written on it.
  • Now there is a pile consisting of $K=2$ face-up cards, on which $2$ and $3$ from the top are written, so these cards are eaten.
• In the $4$-th move, the card with $1$ written on it is stacked, face up, onto the card with $5$ written on it.
  • Now there is a pile consisting of $K=2$ face-up cards, on which $1$ and $5$ from the top are written, so these cards are eaten.
• In the $5$-th move, the card with $4$ written on it is put on the table, face up, without stacked onto any card.
• The card with $4$ written on it was not eaten until the end.

If $K=1$, every card is eaten immediately after put on the table within a single move.
