问题描述

给定一个长度为 $N$ 的序列 $A = (A_1, A_2, \dots, A_N)$。

你需要执行以下操作恰好 $K$ 次：

• 删除 $A$ 的首元素，并在 $A$ 的尾部添加一个 $0$。

请输出经过这些操作后，$A$ 中的所有元素。

Problem Statement

You are given a sequence $A = (A_1, A_2, \dots, A_N)$ of length $N$.
You perform the following operation exactly $K$ times:

• remove the initial element of $A$ and append a $0$ to the tail of $A$.

Print all the elements of $A$ after the operations.

Constraints

• $1 \leq N \leq 100$
• $1 \leq K \leq 100$
• $1 \leq A_i \leq 100$
• All values in the input are integers.

Input

The input is given from Standard Input in the following format:

$N$ $K$

$A_1$ $A_2$ $\dots$ $A_N$

Output

Print the elements of $A$ after the operations in one line, separated by spaces.

Sample Input 1

3 2
2 7 8

Sample Output 1

8 0 0

Before the operations, $A = (2, 7, 8)$.
After performing the operation once, $A = (7, 8, 0)$.
After performing the operation twice, $A = (8, 0, 0)$.
Thus, $(8, 0, 0)$ is the answer.

Sample Input 2

3 4
9 9 9

Sample Output 2

0 0 0

Sample Input 3

9 5
1 2 3 4 5 6 7 8 9

Sample Output 3

6 7 8 9 0 0 0 0 0
