```python3
import sys
input = sys.stdin.readline
from collections import deque

N, L = list(map(int, input().split()))
A = list(map(int, input().split()))
queue = deque()

for i in range(N):
 while queue and queue[-1][0] > A[i]:
 queue.pop()
 queue.append((A[i], i))
 if queue[0][1] <= i - L:
 queue.popleft()
 print(queue[0][0], end=' ')
